Subject: [PATCH 8/9] fbcon: convert last two unregister_con_driver call to
 do_unregister_con_driver


There are only two place use unregister_con_driver now, this patch
convert them to do_unregister_con_driver too, then we can delete
unregister_con_driver whos function can be achieved with do_unregister_con_driver
easily to reduce code size and duplication.
