udp_flow: Remove udp_meta_t from the parameters of udp_flow_from_sock()

Browse Source 
To be used with the vhost-user version of udp.c, we need to export the
udp_flow functions. To avoid to export udp_meta_t too that is specific
to the socket version of udp.c, don't pass udp_meta_t to it,
but the only needed field, s_in.
