btrfs: fix direct I/O read repair for split bios
When a bio is split in btrfs_submit_direct, dip->file_offset contains
the file offset for the first bio. But this means the start value used
in btrfs_check_read_dio_bio is incorrect for subsequent bios. Add
a file_offset field to struct btrfs_bio to pass along the correct offset.
Given that check_data_csum only uses start of an error message this
means problems with this miscalculation will only show up when I/O fails
or checksums mismatch.
The logic was removed in f4f39fc5dc30 ("btrfs: remove btrfs_bio::logical
member") but we need it due to the bio splitting.
