nbd: call nbd_bdev_reset instead of bd_set_size on disconnect
We need to make sure we don't just set the size of the bdev to 0 while it's being used by a file system. We have the appropriate check in nbd_bdev_reset, simply use that helper instead. Signed-off-by: Josef Bacik <jbacik@fb.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
