btrfs: qgroup: Add function qgroup_update_refcnt(). This function is used to update refcnt for qgroups. And is one of the two core functions used in the new qgroup implement. This is based on the old update_old/new_refcnt, but provides a unified logic and behavior. Signed-off-by: Qu Wenruo <quwenruo@cn.fujitsu.com> Signed-off-by: Chris Mason <clm@fb.com>
