e1000: report UDP RSS hash type on igb/em
{em,igb}_determine_rsstype() mapped only the TCP and bare-IP RSS descriptor
types; the UDP types returned M_HASHTYPE_NONE.
The hardware does hash UDP, but with a NONE hashtype iflib skips its
flowid-based TX queue spread, so all forwarded UDP egressed on a single queue
and serialized transmit on one core.
Add the three UDP cases (IPV4_UDP, IPV6_UDP, IPV6_UDP_EX) so egress spreads
across all TX queues.
