Currently we accept any size for the ZA signal context that the shared code will accept which means we don't verify that any data is present. Since we have enabled ZA we know that there must be data so strengthen the check to only accept a signal frame with data, and while we're at it since we enabled ZA but did not set any data we know that ZA must contain zeros, confirm that.
