rbd: have __rbd_add_snap_dev() return a pointer It's not obvious whether the snapshot pointer whose address is provided to __rbd_add_snap_dev() will be assigned by that function. Change it to return the snapshot, or a pointer-coded errno in the event of a failure. Signed-off-by: Alex Elder <elder@inktank.com> Reviewed-by: Josh Durgin <josh.durgin@inktank.com>
