pmap - Missing critical section when calling lwkt_ipiq_process().

- pmap_interlock_wait() explicitly calls lwkt_process_ipiq() which expects to
be in a critical section. We still need cpu_ccfence() to guarantee that
pmap->pm_active is always read inside the loop.

- Sync pmap_interlock_wait's comment for both i386 and x86_64.
