btrfs: remove unit field from struct btrfs_free_space_ctl

Browse source

The unit field always has a value matching the sector size, and since we
have a block group pointer in the structure, we can access the block group
and then its fs_info field to get to the sector size. So remove the field,
which will allow us later to shrink the structure size.
