RDS: TCP: Retransmit half-sent datagrams when switching sockets in rds_tcp_reset_callbacks
When we switch a connection's sockets in rds_tcp_rest_callbacks, any partially sent datagram must be retransmitted on the new socket so that the receiver can correctly reassmble the RDS datagram. Use rds_send_reset() which is designed for this purpose.
