btrfs: qgroup: inherit limit info from srcgroup in creating snapshot.
Currently, when we snapshot a subvol, snapshot will not copy the limits from srcqgroup. This patch make the qgroup in snapshot inherit the limit info when create a snapshot. Signed-off-by: Dongsheng Yang <yangds.fnst@cn.fujitsu.com> Signed-off-by: Chris Mason <clm@fb.com>
