btrfs: block-group: refactor how we read one block group item
Structure btrfs_block_group has the following members which are currently read from on-disk block group item and key: - length - from item key - used - flags - from block group item However for incoming skinny block group tree, we are going to read those members from different sources. This patch will refactor such read by: - Don't initialize btrfs_block_group::length at allocation Caller should initialize them manually. Also to avoid possible (well, only two callers) missing initialization, add extra ASSERT() in btrfs_add_block_group_cache(). - Refactor length/used/flags initialization into one function The new function, fill_one_block_group() will handle the initialization of such members. - Use btrfs_block_group::length to replace key::offset Since skinny block group item would have a different meaning for its key offset.
