bareudp: Fixed bareudp receive handling
Reverted commit "2baecda bareudp: remove unnecessary udp_encap_enable() in
bareudp_socket_create()"
An explicit call to udp_encap_enable is needed as the setup_udp_tunnel_sock
does not call udp_encap_enable if the if the socket is of type v6.
Bareudp device uses v6 socket to receive v4 & v6 traffic
