Xin Long d1bcc60687 erspan: get the proto with the md version for collect_md
[ Upstream commit d80fc101d2eb9b3188c228d61223890aeea480a4 ]

In commit 20704bd1633d ("erspan: build the header with the right proto
according to erspan_ver"), it gets the proto with t->parms.erspan_ver,
but t->parms.erspan_ver is not used by collect_md branch, and instead
it should get the proto with md->version for collect_md.

Thanks to Kevin for pointing this out.

Fixes: 20704bd1633d ("erspan: build the header with the right proto according to erspan_ver")
Fixes: 94d7d8f29287 ("ip6_gre: add erspan v2 support")
