85bba4455a Change pfil starvation prevention from fail-open to fail-close.
We return ENOBUF to indicate the problem, which is an errno that should be
handled well everywhere.

d6a8d58875 Add an additional struct inpcb * argument to pfil(9) in order to enable
passing along socket information. This is required to work around a LOR with
the socket code which results in an easy reproducible hard lockup with
debug.mpsafenet=1. This commit does *not* fix the LOR, but enables us to do
so later. The missing piece is to turn the filter locking into a leaf lock
and will follow in a seperate (later) commit.

This will hopefully be MT5'ed in order to fix the problem for RELENG_5 in
forseeable future.

fa97ea3131 Switch order for mtx_unlock and cv_signal as (condvar(9)) sez:
A thread must hold mp while calling cv_signal(), cv_broadcast(), or
     cv_broadcastpri() even though it isn't passed as an argument.

and is right with this claim.

While here remove a "\" from the macro -> __inline conversion.
