ofp-util: make_packet_out() shouldn't receive OVSP_NONE.

make_packet_out() operates solely at the OpenFlow layer, so it
should never receive OVSP_LOCAL as an in_port.  This function is
used only by the learning switch, which will never generate
a packet with OVSP_LOCAL so this fixes not a bug but a violation
of semantics.
