UNMAP=0 does have a payload, we just ignore it.  In fact I was told
that targets should check for a completely zeroed sector sized payload
for it if being pedantic.  I can't really find the justification for
that in the standard - the closest thing to it is the stance about
ignoring the unmap bit if the device is fully provisioned.
