memory hotplug: migrate swap cache page
In test, some pages in swap-cache can't be migrated, as they aren't rmap.
unmap_and_move() ignores swap-cache page which is just read in and hasn't
rmap (see the comments in the code), but swap_aops provides .migratepage.
Better to migrate such pages instead of ignore them.
