erspan: build the header with the right proto according to erspan_ver
[ Upstream commit 20704bd1633dd5afb29a321d3a615c9c8e9c9d05 ]
As said in draft-foschiano-erspan-03#section4:
Different frame variants known as "ERSPAN Types" can be
distinguished based on the GRE "Protocol Type" field value: Type I
and II's value is 0x88BE while Type III's is 0x22EB [ETYPES].
So set it properly in erspan_xmit() according to erspan_ver. While at
it, also remove the unused parameter 'proto' in erspan_fb_xmit().
Fixes: 94d7d8f29287 ("ip6_gre: add erspan v2 support")
