ofp-util: Ignore unknown fields in ofputil_decode_packet_in2().

The decoder of packet_in messages should not fail on encountering
unknown metadata fields.  This allows the switch to add new features
without breaking controllers.  The controllers should, however, copy
the metadata fields from the packet_int to packet_out so that the
switch gets back the full metadata.  OVN is already doing this.
