geneve: handle ipv6 priority like ipv4 tos
geneve: handle ipv6 priority like ipv4 tos

Other callers of udp_tunnel6_xmit_skb just pass 0 for the prio
argument.  Jesse Gross <a5c95b3d7cb4d0ae05a15c79c79ab458dc2c8f9e@nicira.com> suggested that prio is really
the same as IPv4's tos and should be handled the same, so this is my
interpretation of that suggestion.
