ipv4: Remove erroneous check in igmpv3_newpack() and igmp_send_report().
Output route resolution never returns a route with rt_src set to zero (which is INADDR_ANY). Even if the flow key for the output route lookup specifies INADDR_ANY for the source address, the output route resolution chooses a real source address to use in the final route. This test has existed forever in igmp_send_report() and David Stevens simply copied over the erroneous test when implementing support for IGMPv3. Signed-off-by: David S. Miller <davem@davemloft.net> Reviewed-by: Eric Dumazet <eric.dumazet@gmail.com>
