Revert the NET_LOCK() and bring back pf's contention lock for release.
For the moment the NET_LOCK() is always taken by threads running under
KERNEL_LOCK(). That means it doesn't buy us anything except a possible
deadlock that we did not spot. So make sure this doesn't happen, we'll
have plenty of time in the next release cycle to stress test it.
