blk_throtl_exit() frees the throttle data hanging off the queue in blk_cleanup_queue(), but blk_put_queue() will indirectly dereference this data when calling blk_sync_queue() which in turns calls throtl_shutdown_timer_wq(). Fix this by moving the freeing of the throttle data to when the queue is truly being released, and post the call to blk_sync_queue().
