Currently, udp v6 socket can not process v4 packets with UDP GRO, as
udp_encap_needed_key is not increased when udp_tunnel_encap_enable()
is called for v6 socket. This patchset is to increase it and remove
the unnecessary code in bareudp.

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().

As udp_encap_enable() is already called in udp_tunnel_encap_enable()
since the last patch, and we don't need it any more. So remove it by
reverting commit 81f954a44567567c7d74a97b1db78fb43afc253d.

I will add udp_encap_disable() and export, thanks.
