Jason Gunthorpe 068354ade5 mm/hmm: remove pgmap checking for devmap pages
The checking boils down to some racy check if the pagemap is still
available or not. Instead of checking this, rely entirely on the
notifiers, if a pagemap is destroyed then all pages that belong to it must
be removed from the tables and the notifiers triggered.
