Petr Machata a6465350ef net: ip6_gre: Split up ip6gre_tnl_change()
Split a reusable function ip6gre_tnl_copy_tnl_parm() from
ip6gre_tnl_change(). This will allow ERSPAN-specific code to
reuse the common parts while customizing the behavior for ERSPAN.

Fixes: 5a963eb61b7c ("ip6_gre: Add ERSPAN native tunnel support")
