MD Danish Anwar a2dc179481 net: hsr: enable promiscuous mode on interlink port with fwd offload 
hsr_portdev_setup() skips promiscuous mode on non-master ports when
hsr->fwd_offloaded is set. fwd_offloaded is derived only from the ring
slaves' NETIF_F_HW_HSR_FWD bit, so this also skips it for the interlink
port, which never gets forwarding offload. Without promiscuous mode,
the interlink NIC drops unicast frames addressed to hsr_dev's MAC
(e.g. SAN traffic to the RedBox), breaking RedBox whenever the ring is
HW-offloaded.
