The done() function is called with a host_byte indicating the actual error when the message byte is set. As the host byte takes precedence during error recovery we can drop setting the message byte if the host byte is set, too. The only other case is when the host byte is DID_OK, but in that case the message byte is always COMMAND_COMPLETE (ie 0), so we can drop it there, too.
