ANDROID: set emulate_zone_append=true in dm-default-key

All zone append writes to a zone of a zoned block device will
have the same BIO sector, the start of the zone. When the
cypher IV mode uses sector values, all data targeting a
zone will be encrypted using the first sector numbers of the
zone. This will not result in write errors but will
cause most reads to fail as reads will use the sector values
for the actual data locations, resulting in IV mismatch.
To avoid this problem, ask DM core to emulate zone append
operations with regular writes.
