mm: migration: do not lose soft dirty bit if page is in migration state
If page migration is turned on in config and the page is migrating, we
may lose the soft dirty bit. If fork and mprotect are called on
migrating pages (once migration is complete) pages do not obtain the
soft dirty bit in the correspond pte entries. Fix it adding an
appropriate test on swap entries.
