block: fix surprise removal for drivers calling blk_set_queue_dying
Various block drivers call blk_set_queue_dying to mark a disk as dead due
to surprise removal events, but since commit 8e141f9eb803 that doesn't
work given that the GD_DEAD flag needs to be set to stop I/O.
Replace the driver calls to blk_set_queue_dying with a new (and properly
documented) blk_mark_disk_dead API, and fold blk_set_queue_dying into the
only remaining caller.
Fixes: 8e141f9eb803 ("block: drain file system I/O on del_gendisk")
