Diff below turns i386's pmap_collect() into a noop like it is on
amd64/arm64/powerpc64... This is part of the UVM unlocking diff and
might no longer be necessary now that pmap_extract() has been fixed.
So I'd like to know if we want to align i386's behavior with other
archs, which should help us debug MI issues or if I drop this diff.
Since sthen@ tested it, I'd be in favor of putting it in. ok?
