ena: Convert not-right membar_enter/exit to membar_acquire/release.

Only used on non-x86 and non-aarch64, which probably means this
branch is never used.  (This should really use bus_space_barrier or
bus_dmamap_sync.)

ena: Fix rmb/wmb/mb to match Linux on x86 and aarch64.

This is not right but it's not worse than it was before.

Various ena(4) bug fixes, from KUSABA Takeshi <t-kusaba@iij.ad.jp>:

[PATCH 07/32] fix null check target.
[PATCH 08/32] use if_initialize() and if_register() instead of
[PATCH 09/32] free all pci-related resource.

Revert previous for now:
http://mail-index.netbsd.org/source-changes/2020/04/16/msg116278.html

The reasoning turned out to be wrong; __KERNEL_RCSID() in header files
does *not* overwrite RCSID in main source files. The real problem is that
it inserts its RCSID into *every* object files. However, it can be still
useful even if heavily duplicated.

Stop using __KERNEL_RCSID() in header files; it confuses ident(1) by
overwriting RCSID in main source files.

XXX
The first argument of __KERNEL_RCSID() is neglected for ELF. If we wish
to have RCSID of header files in kernel binary, we need something like
__FBSDID() macro in FreeBSD.

make ena(4) compile, with best efford exercised to convert code to NetBSD
equivalents; where possible left the original code intact to make it
easier to compare against FreeBSD original

made non-working stubs for some functions which don't have direct
equivalent yet - this includes all of <sys/buf_ring.h>, m_getjcl(),
m_append, and m_collapse(); these need to be adressed

left XXX/TODO in if_enavar.h, colocated with the non-working stubs
