However after finishing quota rescan, we set fs_info->qgroup_rescan_progress to (u64)-1 before we exit through the original exit path. While we missed that assignment of (u64)-1 in the new exit path. The end result is, the quota status item doesn't have the same value. (-1 vs the last bytenr + 1) Although it doesn't affect quota accounting, it's still better to keep the original behavior.
