ip6_gre: fix flowi6_proto value in xmit path
[ Upstream commit 3be07244b7337760a3269d56b2f4a63e72218648 ]
In xmit path, we build a flowi6 which will be used for the output route lookup.
We are sending a GRE packet, neither IPv4 nor IPv6 encapsulated packet, thus the
protocol should be IPPROTO_GRE.
Fixes: c12b395a4664 ("gre: Support GRE over IPv6")
