dpif-netlink: For non-Ethernet, use Ethertype from packet_type.

For non-Ethernet flows, when fixing up the netlink message we need make
sure to pass down a valid Ethertype. The kernel does not understand
packet_type so it's implicitly encoded by the absence of _ETHERNET and
exact match of _ETHERTYPE. Without this change match_validate in the
kernel complains when trying to match packets from L3 tunnels.
e.g.
  openvswitch: netlink: Unexpected mask (mask=110088, allowed=3d9804c)

The mask use to always be set in xlate_wc_init() and xlate_wc_finish(),
but that changed for non-Ethernet frames with the commit listed below.

Fixes: 3d4b2e6eb74e ("userspace: Add OXM field MFF_PACKET_TYPE")
