bonding: set correct vlan id for alb xmit path

The commit d3ab3ffd1d728d7ee77340e7e7e2c7cfe6a4013e
(bonding: use rlb_client_info->vlan_id instead of ->tag)
remove the rlb_client_info->tag, but occur some issues,
The vlan_get_tag() will return 0 for success and -EINVAL for
error, so the client_info->vlan_id always be set to 0 if the
vlan_get_tag return 0 for success, so the client_info would
never get a correct vlan id.

We should only set the vlan id to 0 when the vlan_get_tag return error.

Fixes: d3ab3ffd1d7 (bonding: use rlb_client_info->vlan_id instead of ->tag)
