mm/gup: longterm pin migration cleanup

When pages are longterm pinned, we must migrated them out of movable zone.
The function that migrates them has a hidden loop with goto.  The loop is
to retry on isolation failures, and after successful migration.

Make this code better by moving this loop to the caller.
