chunk type BTRFS_BLOCK_GROUP_METADATA and BTRFS_BLOCK_GROUP_DATA
should not be set in a non-mixed chunk at the same time.
Since BTRFS_BLOCK_GROUP_METADATA is 0x4 and BTRFS_BLOCK_GROUP_DATA is 0x1,
BTRFS_BLOCK_GROUP_METADATA & BTRFS_BLOCK_GROUP_DATA will be 0x0,
so we should judge type is one of them separately.
