Commit ff3d27a048d9 ("btrfs: qgroup: Finish rescan when hit the last leaf of extent tree")
added a new exit for rescan finish.
However after finishing quota rescan, we set
fs_info->qgroup_rescan_progress to (u64)-1, as qgroup_rescan_progress is also
used to determine whether we should account dirty extents.
Since if dirty extents is after qgroup_rescan_progress, we don't need to
account it as rescan will account them later.
Without properly setting qgroup_rescan_progress to (u64)-1, all later
dirty extents after qgroup_rescan_progress will be ignored, thus
screwing up the whole quota accounting.
