cfq_get_queue: fix possible NULL pointer access
cfq_get_queue()->cfq_find_alloc_queue() can fail, check the returned value. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Note that this isn't a bug at the moment, since the regular IO path does not call this path without __GFP_WAIT set. However, it could be a future bug, so I've applied it. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
