Konstantin Belousov 1614716655 Save a call to pmap_remove() if entry cannot have any pages mapped.
Due to the way rtld creates mappings for the shared objects, each dso
causes unmap of at least three guard map entries.  For instance, in
the buildworld load, this change reduces the amount of pmap_remove()
calls by 1/5.
