icmp: ICMPV6: pass RFC 8335 reply messages to ping_rcv
The current icmp_rcv function drops all unknown ICMP types, including ICMP_EXT_ECHOREPLY (type 43). In order to parse Extended Echo Reply messages, we have to pass these packets to the ping_rcv function, which does not do any other filtering and passes the packet to the designated socket. Pass incoming RFC 8335 ICMP Extended Echo Reply packets to the ping_rcv handler instead of discarding the packet.
