btrfs: fix file_offset for REQ_BTRFS_ONE_ORDERED bios that get split
If a bio gets split, it needs to have a proper file_offset for checksum
validation and repair to work properly.
Based on feedback from Josef, commit 852eee62d31a ("btrfs: allow
btrfs_submit_bio to split bios") skipped this adjustment for ONE_ORDERED
bios. But if we actually ever need to split a ONE_ORDERED read bio, this
will lead to a wrong file offset in the repair code. Right now the only
user of the file_offset is logging of an error message so this is mostly
harmless, but the wrong offset might be more problematic for additional
users in the future.
