rbd: return -ENOMEM instead of pool id if rbd_dev_create() fails
Returning pool id (i.e. >= 0) from a sysfs ->store() callback makes userspace think it needs to retry the write. Fix it - it's a leftover from the times when the equivalent of rbd_dev_create() was the first action in rbd_add(). Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
