btrfs: zoned: don't zone append to conventional zone

Browse source

In case of a zoned RAID, it can happen that a data write is targeting a
sequential write required zone and a conventional zone. In this case the
bio will be marked as REQ_OP_ZONE_APPEND but for the conventional zone,
this needs to be REQ_OP_WRITE.

The setting of REQ_OP_ZONE_APPEND is deferred to the last possible time in
btrfs_submit_dev_bio(), but the decision if we can use zone append is
cached in btrfs_bio.
