net/ipv6/udp: Fix ipv6 multicast socket filter regression
Commit <5cf3d461 > ("udp: Simplify__udp*_lib_mcast_deliver") simplified the filter for incoming IPv6 multicast but removed the check of the local socket address and the UDP destination address. This patch restores the filter to prevent sockets bound to a IPv6 multicast IP to receive other UDP traffic link unicast.
