sys: Drop redundant NULL check before m_freem(9)

m_freem(9) safely has accepted NULL argument at least since 4.2BSD:

Compile-tested on amd64/ALL.

update from HEAD

Sync with HEAD

Catch up with the renaming of module ppp --> if_ppp and avoid warning
messages at boot (or module load) time.

Modularize the ppp driver, and adjust dependencies of the compressor
modules.

For now, this is still included as a built-in module in GENERIC kernels.

Sync with HEAD

Add modular dependency on zlib module.

kill MALLOC and FREE macros.

Update haad-dm branch to haad-dm-base2.

Fix handling of ppp compressor modules, from Andrew Doran's input.
 - ref count each compressor
 - allow {un,}registration of several modules at once
 - une RUN_ONCE to make sure the mutex is initialised, because
   unfortunately built-in (and bootloader-loaded) modules init functions
   are run before pseudo-devices attach (reported by Nick Hudson).

Rework the way PPP compmressors are handled and allow them to be
automatically loaded when needed.

Back out previous. It broke the build.

Move zlib out of net/ and into kern/. It would probably be better to use
the reachover Makefiles and libz, but this is already here and it works.

__unused removal on arguments; approved by core.

ANSI function decls and application of static.

sync kqueue with -current; this includes merge of gehenna-devsw branch,
merge of i386 MP branch, and part of autoconf rototil work

Catch up to -current.

copyright clarification.  from openbsd

1.
Paul Mackerras and the Australian National University have worked things
out, and as a result, Paul now owns copyright on all these files, with the
proper terms.

2.
and... we managed to contact "Eric Rosenquist" <eric@rosenquist.com> through
the help of people who found him: first one was nick.stott@cogeco.ca
This now has a better license.  Two authors left to go.

Catch up to -current.
(CVS: It's not just a program. It's an adventure!)

Pull up revision 1.11 (requested by fvdl):
  Fix a problem related to compression which would cause a lot of
  logged incorrect warnings.

Catch up with -current.

Fix what looks like a merge error: olen = 0 in z_decompress, not
PPP_HDRLEN, which caused lots of 'ppp_deflate0: exceeded mru (1508 > 1504)'
messages.

Sync kqueue branch with -current.

don't need <sys/types.h> when including <sys/param.h>

Catch up to -current.

add RCSIDs

update to -current

bzero -> memset

Update thorpej_scsipi to -current as of a month ago

Don't use MALLOC() for variable-sized allocations.

Merge changes from pppd-2.3.4; adds ppp-deflate-draft stuff and updates
zlib. Maybe we can merge our other copy of zlib with this one now and
avoid having two copies?

Update to ppp-2.3b5

Update to ppp-2.3b4; from Paul Mackerras

backout previous kprintf change

- printf -> kprintf, sprintf -> ksprintf

Added packet filtering, support for "PPP Deflate" packet compression,
trivial multicast support, and support for xon/xoff output flow
control to the PPP subsystem.  Fixed several bugs, including making
the accumulation and resetting of statistics more consistent.  State
for the VJ compressor is now dynamically allocated.
