Gleb Smirnoff ea53792942 Fix races between in_lltable_prefix_free(), lla_lookup(), 
llentry_free() and arptimer():

o Use callout_init_rw() for lle timeout, this allows us safely
  disestablish them.
  - This allows us to simplify the arptimer() and make it
    race safe.
o Consistently use ifp->if_afdata_lock to lock access to
  linked lists in the lle hashes.
o Introduce new lle flag LLE_LINKED, which marks an entry that
  is attached to the hash.
  - Use LLE_LINKED to avoid double unlinking via consequent
    calls to llentry_free().
  - Mark lle with LLE_DELETED via |= operation istead of =,
    so that other flags won't be lost.
o Make LLE_ADDREF(), LLE_REMREF() and LLE_FREE_LOCKED() more
  consistent and provide more informative KASSERTs.

The patch is a collaborative work of all submitters and myself.
