xfrm: fix inbound ipv4/udp/esp packets to UDPv6 dualstack sockets
[ Upstream commit 1166a530a84758bb9e6b448fc8c195ed413f5ded ]
Before Linux v5.8 an AF_INET6 SOCK_DGRAM (udp/udplite) socket
with SOL_UDP, UDP_ENCAP, UDP_ENCAP_ESPINUDP{,_NON_IKE} enabled
would just unconditionally use xfrm4_udp_encap_rcv(), afterwards
such a socket would use the newly added xfrm6_udp_encap_rcv()
which only handles IPv6 packets.
