ANDROID: block: Do not set the I/O priority for zoned writes

The I/O priority set by the ionice command or by the blk-ioprio cgroup
policy may cause the mq-deadline I/O scheduler to submit zoned writes in
the wrong order and hence to trigger unaligned write errors. Fix this by
not applying these I/O priority policies on sequential zoned writes.
