btrfs: fix direct I/O writes for split bios on zoned devices

Browse source

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_end_dio_bio to record the write location for zone devices is
incorrect for subsequent bios.
