The machine-independent parts of the virtual memory system always pass a

valid pmap to the pmap functions that require one.  Remove the checks for
NULL.  (These checks have their origins in the Mach pmap.c that was
integrated into BSD.  None of the new code written specifically for
FreeBSD included them.)
