When we have a page fault for the address which is backed by a hugepage
under migration, the kernel can't wait correctly until the migration
finishes. This is because pte_offset_map_lock() can't get a correct
migration entry for hugepage. This patch adds migration_entry_wait_huge()
to separate code path between normal pages and hugepages.
ChangeLog v2:
- remove dup in migrate_entry_wait_huge()
