net: ip6_gre: Split up ip6gre_tnl_link_config()
The function ip6gre_tnl_link_config() is used for setting up
configuration of both ip6gretap and ip6erspan tunnels. Split the
function into the common part and the route-lookup part. The latter then
takes the calculated header length as an argument. This split will allow
the patches down the line to sneak in a custom header length computation
for the ERSPAN tunnel.
Fixes: 5a963eb61b7c ("ip6_gre: Add ERSPAN native tunnel support")
