learning-switch: Fix coredump of OpenFlow15 learning-switch.
The OpenFlow15 Packet-Out message contains the match instead of the
in_port. The flow.tunnel.metadata.tab is not inited but used in the
loop of tun_metadata_to_nx_match.
The coredump gdb backtrace is:

Fix that by initing the flow metadata.
