Kristof Provost 2f8fb3a868 pf: Fix possible shutdown race 
Prevent possible races in the pf_unload() / pf_purge_thread() shutdown
code. Lock the pf_purge_thread() with the new pf_end_lock to prevent
these races.

Use a shared/exclusive lock, as we need to also acquire another sx lock
(VNET_LIST_RLOCK). It's fine for both pf_purge_thread() and pf_unload()
to sleep,
