btrfs: fix qgroup_free wrong num_bytes in btrfs_subvolume_reserve_metadata
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.
Delete the comment for the qgroup_reserved that does not exist and add a
comment about use_global_rsv.
Fixes: c4c129db5da8 ("btrfs: drop unused parameter qgroup_reserved")
