ip_gre: do not report erspan version on GRE interface
Although the type I ERSPAN is based on the barebones IP + GRE
encapsulation and no extra ERSPAN header. Report erspan version on GRE
interface looks unreasonable. Fix this by separating the erspan and gre
fill info.
IPv6 GRE does not have this info as IPv6 only supports erspan version
1 and 2.
