[PATCH 7/7] nbd: call nbd_bdev_reset instead of bd_set_size on disconnect

[Josef Bacik]

From: Josef Bacik <jba...@fb.com>

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.
