When qgroup is on, subvolume deletion does not remove qgroup items
of the subvolume (qgroup info, limit, relation) from quota tree and
they need to get removed manually by "btrfs qgroup destroy".
Since level 0 qgroup cannot be used/inherited by any other subvolume,
let's remove them automatically
In btrfs_remove_qgroup(), each qgroup relation is removed by calling
__del_qgroup_relation(). However, __del_qgroup_relation() returns 1
if deletion of qgroup relation causes inconsistency and current code
exits immediately in that case.
Therefore if there are several qgroup relations and
After btrfs_qgroup_reserve_meta_prealloc(), num_bytes will be assigned
again by btrfs_calc_trans_metadata_size(). Once block_rsv fails, we can't
properly free the num_bytes of the previous qgroup_reserve. Use a separate
variable to store the num_bytes of the qgroup_reserve.

When quota is enabled and we do a snapshot, we just update the 'excl'
number of both snapshot src and dst to src's 'rfer' - nodesize.
It's a quick hack to avoid quota rescan every time we create a snapshot
and it works if src doesn't belong to other qgroups.
But if we have higher level qgroups,
