Mark Johnston e1cb9d3747 Busy the map in vm_map_protect(). ...

We are otherwise susceptible to a race with a concurrent vm_map_wire(),
which may drop the map lock to fault pages into the object chain. In
particular, vm_map_protect() will only copy newly writable wired pages
into the top-level object when MAP_ENTRY_USER_WIRED is set, but
vm_map_wire() only sets this flag after its fault loop. We may thus end
up with a writable wired entry whose top-level object does not contain the
entire range of pages.
