btrfs: qgroup: Avoid calling btrfs_free_reserved_data_space in clear_bit_hook
In clear_bit_hook, qgroup reserved data is already handled quite well, either released by finish_ordered_io or invalidatepage. So calling btrfs_qgroup_free_data() here is completely meaningless, and since btrfs_qgroup_free_data() will lock io_tree, so it can't be called with io_tree lock hold. This patch will add a new function btrfs_free_reserved_data_space_noquota() for clear_bit_hook() to cease the lockdep warning.
