udp: Always use sendto() rather than send() for forwarding spliced packets
udp_sock_handler_splice() has two different ways of sending out packets once it has determined the correct destination socket. For the originating sockets (which are not connected) it uses sendto() to specify a specific address. For the forward socket (which is connected) we use send(). However we know the correct destination address even for the forward socket we do also know the correct destination address. We can use this to use sendto() instead of send(), removing the need for two different paths and some staging data structures.
