        src/sys/net: if_llatbl.c

Log Message:
Fix race condition on la_rt between lltable_free and other places touching la_rt

We have to touch la_rt always with holding softnet_lock. And we have to
use callout_halt with softnet_lock instead of callout_stop for
la_timer (arptimer) because arptimer holds softnet_lock inside it.

This fix may solve a kernel panic christos@ encountered.
