When enabling encap for a ipv6 socket without udp_encap_needed_key
increased, UDP GRO won't work for v4 mapped v6 address packets as
sk will be NULL in udp4_gro_receive().
This patch is to enable it by increasing udp_encap_needed_key for
v6 sockets in udp_tunnel_encap_enable(), and correspondingly
decrease udp_encap_needed_key in udpv6_destroy_sock().
v1->v2:
- add udp_encap_disable() and export it.
v2->v3:
- add the change for rxrpc and bareudp into one patch, as Alex
suggested.
v3->v4:
- move rxrpc part to another patch.
