Chris Mason 1a81af4d1d Btrfs: make sure btrfs_update_delayed_ref doesn't increase ref_mod ... btrfs_update_delayed_ref is optimized to add and remove different references in one pass through the delayed ref tree. It is a zero sum on the total number of refs on a given extent. But, the code was recording an extra ref in the head node. This never made it down to the disk but was used when deciding if it was safe to free the extent while dropping snapshots. The fix used here is to make sure the ref_mod count is unchanged on the head ref when btrfs_update_delayed_ref is called.
