Subject: [PATCH 6/6]NET:AX25:ROSE Removes a conditional return and corrects the return value.
Removes a conditional return and corrects the return value.

The ROSE header is always finished (as it is not dependant on daddr) so
the test for daddr is not required.

Return value fixed as positive added header length.
