btrfs: introduce BTRFS_QGROUP_STATUS_FLAGS_MASK for later expansion
Currently we only have 3 qgroup flags:
- BTRFS_QGROUP_STATUS_FLAG_ON
- BTRFS_QGROUP_STATUS_FLAG_RESCAN
- BTRFS_QGROUP_STATUS_FLAG_INCONSISTENT
These flags match the on-disk flags used in btrfs_qgroup_status.
But we're going to introduce extra runtime flags which will not reach
disks.
So here we introduce a new mask, BTRFS_QGROUP_STATUS_FLAGS_MASK, to
make sure only those flags can reach disks.
