net/smc: cleanup of get vlan id
The vlan_id of the underlying CLC socket was retrieved two times during processing of the listen handshaking. Change this to get the vlan id one time in connect and in listen processing, and reuse the id. And add a new CLC DECLINE return code for the case when the retrieval of the vlan id failed.
