btrfs: limit write bios to a single ordered extent
Currently buffered writeback bios are allowed to span multiple
ordered_extents, although that basically never actually happens since
commit 4a445b7b6178 ("btrfs: don't merge pages into bio if their page
offset is not contiguous").
Supporting bios than span ordered_extents complicates the file
checksumming code, and prevents us from adding an ordered_extent pointer
to the btrfs_bio structure. Use the existing code to limit a bio to
single ordered_extent for zoned device writes for all writes.
This allows to remove the REQ_BTRFS_ONE_ORDERED flags, and the
handling of multiple ordered_extents in btrfs_csum_one_bio.
