So Andrew suggested just removing the BUG_ON(), but it's been there
for a *long* time.

And I detest the patch that was sent out that said "Should I check?"

Maybe we should just remove that mlock_vma_page() thing instead in
try_to_unmap_cluster()? Or maybe actually lock the page around calling
it?
