btrfs: use the enums instead of int type in struct btrfs_block_group fields

The 'disk_cache_state' and 'cached' fields are defined with an int type
but all the values we assigned to them come from the enums
btrfs_disk_cache_state and btrfs_caching_type. So change the type in the
btrfs_block_group structure from int to these enums - in practice an enum
is an int, so this is more for readability and clarity.
