Log Message:
Work around the problem that causes kern/12554.  Basically,
there are some pathological cases that cause pmap_page_protect()
to be called on a wired page to revoke all mappings.  We
need to skip mappings that are actually wired to prevent Bad
things from happening later.

THIS IS JUST A WORK-AROUND.  We need to prevent the pathological
behavior from happening in UVM to begin with.  But it's unclear
what the right solution is there, right now.
