ipvlan: fix incorrect usage of IS_ERR() macro in IPv6 code path.
The ip6_route_output() always returns a valid dst pointer unlike in IPv4
case. So the validation has to be different from the IPv4 path. Correcting
that error in this patch.
This was picked up by a static checker with a following warning -
drivers/net/ipvlan/ipvlan_core.c:380 ipvlan_process_v6_outbound()
warn: 'dst' isn't an ERR_PTR
