am65_cpsw_nuss_ndo_slave_add_vid() returns early at the top with:
if (!netif_running(ndev) || !vid)
return 0;
so vid is guaranteed to be non-zero in the rest of the function. The
subsequent
if (!vid)
unreg_mcast = port_mask;
is therefore unreachable. Drop the dead branch.
With that branch gone, unreg_mcast is only ever its initializer value
of zero, so drop the variable and pass 0 directly to
cpsw_ale_vlan_add_modify().
No functional change.
