Subject: mlx5: ensure 0 is returned when vport is zero
Patch-mainline: v4.14-rc1
Git-commit: 1547f538c14581346c2eb82f8af0071ee6ec2b30
References: bsc#1046305 FATE#322943
Currently, if vport is zero then then an uninialized return status
in err is returned. Since the only return status at the end of the
function esw_add_uc_addr is zero for the current set of return paths
we may as well just return 0 rather than err to fix this issue.
