udp: Remove obsolete splice tracking

Now that spliced datagrams are managed via the flow table, remove
UDP_ACT_SPLICE_NS and UDP_ACT_SPLICE_INIT which are no longer used.  With
those removed, the 'ts' field in udp_splice_port is also no longer used.
struct udp_splice_port now contains just a socket fd, so replace it with
a plain int in udp_splice_ns[] and udp_splice_init[].  The latter are still
used for tracking of automatic port forwarding.

Finally, the 'splice' field of union udp_epoll_ref is no longer used so
remove it as well.
