btrfs: qgroup: fix off-by-one max level check in qgroup_trace_new_subtree_blocks()
We have maximum of 8 (BTRFS_MAX_LEVEL) levels in a btree, going from 0 to
7, so the upper bound checks should be:
>= BTRFS_MAX_LEVEL
and not:
>= BTRFS_MAX_LEVEL - 1
In practice this will hardly ever be a problem since having a btree with
8 levels would imply a massively huge fs.
