lagg(4): Remove unnecessary LAGG_LOCK holding while lagg_proto_detach()
to avoid deadlock in workqueue_wait due to LAGG_LOCK holding

lagg_proto_detach dose not need to hold LAGG_LOCK because only one
context can access to a detaching protocol after sc->sc_var is updated.
But it was held without any reason. And it had caused a deadlock by
holding LAGG_LOCK in caller of workqueue_wait
and waiting for the lock in worker.

Fix to call lacp_linkstate with IFNET_LOCK held

Network stack calls lacp_linkstate through lagg_port_ioctl when
doing "ifconfig up" or "ifconfig down" to an interface that is
a member of lagg(4). And IFNET_LOCK in the member interface
is held while the ioctl.
Therefore, lacp_linkstate is renamed to
lacp_linkstate_ifnet_locked, and always called with IFNET_LOCK
held. It avoids locking agains myself.

lagg(4): Need to take IFNET_LOCK around if_init.

This should really just avoid dropping IFNET_LOCK before it's done

will serve provisionally to reduce crashes until we can confirm that
there's no deadlock lurking in the time this logic drops IFNET_LOCK.

Fix to acquire LAGG_LOCK without psref
to remove possibility of deadlock

the deadlock maybe happened between lagg_ifdetach()
and lagg_delport()

1. lagg_ifdetach calls psref_target_acquire()
2. lagg_delport calls LAGG_LOCK()
3. lagg_ifdetach calls LAGG_LOCK()
   - wait for lagg_delport
4. lagg_delport calls psref_target_destroy()
   - wait for lagg_ifdetach

if_attach and if_initialize cannot fail, don't test return value

These were originally made failable back in 2017 when if_initialize
allocated a softint in every interface for link state changes, so
that it could fail gracefully instead of panicking:

https://mail-index.NetBSD.org/source-changes/2017/10/23/msg089053.html

However, this spawned many seldom- or never-tested error branches,
which are risky to have around.  And that softint in every interface
has since been replaced by a single global workqueue, because link
state changes require thread context but not low latency or high
throughput:

https://mail-index.NetBSD.org/source-changes/2020/02/06/msg113759.html

So there is no longer any reason for if_initialize to fail.  (The
subroutine if_stats_init can't fail because percpu_alloc can't fail
either.)

There is a snag: the softint_establish in if_percpuq_create could
fail, potentially leading to bad consequences later on trying to use
the softint.  This change doesn't introduce any new bugs because of
the snag -- if_percpuq_attach was already broken.  However, the snag
can be better addressed without spawning error branches, either by
using a single softint or making softints less scarce.

(Separate commit will change the signatures of if_attach and
if_initialize to return void, scheduled to ride whatever is the next
convenient kernel bump.)
