net/smc: remove the fallback in __smc_connect

When the SMC client begins to connect to server, smcd_version is set
to SMC_V1 + SMC_V2. If fail to get VLAN ID, only SMC_V2 information
is left in smcd_version. And smcd_version will not be changed to 0.
Therefore, remove the fallback caused by the failure to get VLAN ID.
