null_blk: Cleanup error recovery in null_add_dev() When creation of queues fails in init_driver_queues(), we free the queues. But null_add_dev() doesn't test for this failure and continues with the setup leading to strange consequences, likely oops. Fix the problem by testing whether init_driver_queues() failed and do proper error cleanup. Coverity-id: 1148005 Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Jens Axboe <axboe@fb.com>
