Alan Cox caa665aae3 Undo revision 1.251. This change was a performance pessimizing work-around
that is no longer required.  (In fact, it is not clear that it was ever
required in HEAD or RELENG_4, only RELENG_3 required a work-around.)  Now,
as before revision 1.251, if the preexisting PTE is invalid, pmap_enter()
does not call pmap_invalidate_page() to update the TLB(s).

Note: Even with this change, the handling of a copy-on-write fault is
inefficient, in such cases pmap_enter() calls pmap_invalidate_page() twice.
