Cong WangandGreg Kroah-Hartman 0d6eeee3b9 erspan: fix version 1 check in gre_parse_header() 
[ Upstream commit 085c7c4e1c ]

Both version 0 and version 1 use ETH_P_ERSPAN, but version 0 does not
have an erspan header. So the check in gre_parse_header() is wrong,
we have to distinguish version 1 from version 0.

We can just check the gre header length like is_erspan_type1().

Fixes: cb73ee40b1 ("net: ip_gre: use erspan key field for tunnel lookup")
