net: ip: make ip_mc_validate_source() return drop reason
Make ip_mc_validate_source() return drop reason, and adjust the call of
it in ip_route_input_mc().
Another caller of it is ip_rcv_finish_core->udp_v4_early_demux, and the
errno is not checked in detail, so we don't do more adjustment for it.
The drop reason "SKB_DROP_REASON_IP_LOCALNET" is added in this commit.
