geneve: fix populating tclass in geneve_get_v6_dst
The struct flowi6's flowi6_tos is not used in IPv6 route lookup, the
traffic class information is handled in the flowi6's flowlabel member
instead. For example, for policy routing, fib6_rule_match() uses
ip6_tclass() that is applied on the flowlabel for matching on tclass,
which would currently not work as expected.
Fixes: 3a56f86f1be6 ("geneve: handle ipv6 priority like ipv4 tos")
