block: handle REQ_OP_ZONE_APPEND in __bio_integrity_action

block: handle REQ_OP_ZONE_APPEND in __bio_integrity_action

Otherwise zone append commands will miss their integrity data.  While
this works "fine" for auto-PI, it break file system PI and non-PI
metadata.

With this XFS on ZNS namespace with non-PI metadata and 512 byte sectors
with PI work, while PI 4k sector formats with PI work only when Caleb's
"block: fix integrity offset/length conversions" is applied as well.

Note that unlike regular writes, zone append does need remapping as
partitions are not supported on zoned block devices.
