[PATCH 3/7] btrfs: use proper types for btrfs_block_group fields

[Sun YangKai <sunk67188@gmail.com>]

Convert disk_cache_state and cached fields in struct btrfs_block_group
from int to their respective enum types (enum btrfs_disk_cache_state
and enum btrfs_caching_type). Also change btrfs_block_group_done() to
return bool instead of int since it returns a boolean comparison.

No functional changes intended.
