btrfs: use temporary variable for space_info in btrfs_update_block_group
We do cache->space_info->counter += num_bytes; everywhere in here. This is makes the lines longer than they need to be, and will be especially noticeable when we add the active tracking in, so add a temp variable for the space_info so this is cleaner.
