[PATCH] scsi: libcxgbi: in case of vlan pass 0 as ifindex to find route

[Varun Prakash]

In case of vlan pass 0 as ifindex to find route instead of
passing real_dev ifindex, if we pass real_dev ifindex
then ip_route_output_ports() and ip6_route_output() will
check for route through real_dev not through vlan interface.
