udp: no longer touch sk->sk_refcnt in early demux
After commits ca065d0cf80f ("udp: no longer use SLAB_DESTROY_BY_RCU")
and 7ae215d23c12 ("bpf: Don't refcount LISTEN sockets in sk_assign()")
UDP early demux no longer need to grab a refcount on the UDP socket.
This save two atomic operations per incoming packet for connected
sockets.
