btrfs: remove btrfs_bio::logical member
The member btrfs_bio::logical is only initialized by two call sites:
- btrfs_repair_one_sector()
No corresponding site to utilize it.
- btrfs_submit_direct()
The corresponding site to utilize it is btrfs_check_read_dio_bio().
However for btrfs_check_read_dio_bio(), we can grab the file_offset from
btrfs_dio_private::file_offset directly.
Thus it turns out we don't really need that btrfs_bio::logical member at
all.
For btrfs_bio, the logical bytenr can be fetched from its
bio->bi_iter.bi_sector directly.
So let's just remove the member to save 8 bytes for structure btrfs_bio.
