block: add proper state guards to __elv_next_request
blk_cleanup_queue() calls elevator_exit() and after this, we can't touch the elevator without oopsing. __elv_next_request() must check for this state because in the refcounted queue model, we can still call it after blk_cleanup_queue() has been called. This was reported as causing an oops attributable to scsi. Signed-off-by: James Bottomley <James.Bottomley@suse.de> Cc: stable@kernel.org Signed-off-by: Jens Axboe <jaxboe@fusionio.com>
