btrfs: use file_offset to limit bios size in calc_bio_boundaries
btrfs_ordered_extent->disk_bytenr can be rewritten by the zoned I/O
completion handler, and thus in general is not a good idea to limit I/O
size. But the maximum bio size calculation can easily be done using the
file_offset fields in the btrfs_ordered_extent and btrfs_bio structures,
so switch to that instead.
