[PATCH] btrfs: zoned: revert mistakenly removed space accounting

[Naohiro Aota]

The commit ee1cd63d10a8 ("btrfs: convert block group bit field to use bit
helpers") removed an accounting of space_info->active_total_bytes, maybe by
mistake. Revert it back to make the active zone tracking properly work
again.
