Correct two pessimizations in pmap_extract_and_hold(). Test the PTE for
having PTE_RO set instead of PTE_D. This avoids some unnecessary failures
by pmap_extract_and_hold() that will have to be handled by a call to
vm_fault_hold(). Testing the PTE for both being non-zero and having PTE_V
set is redundant. The latter suffices.
