Log Message:
Apply patch, requested by bouyer in ticket #1075:

        sys/arch/x86/x86/pmap.c (apply patch)

Fix double count on ptp entries in pmap_enter_gnt(), which causes a KASSERT
at pmap_destroy() time. Call pmap_free_ptp() if needed. We can have a 0 wire
count if we had an old mapping and grant map hypercall failed,
and this was the only page in this ptp.

while there remove ptp != NULL checks for gnt operations: we always have
a ptp here.
