Lorenzo Bianconi 4523bc8640 net: ip6_gre: initialize erspan_ver just for erspan tunnels
[ Upstream commit 4974d5f678 ]

After commit c706863bc8 ("net: ip6_gre: always reports o_key to
userspace"), ip6gre and ip6gretap tunnels started reporting TUNNEL_KEY
output flag even if it is not configured.
ip6gre_fill_info checks erspan_ver value to add TUNNEL_KEY for
erspan tunnels, however in commit 84581bdae9 ("erspan: set
erspan_ver to 1 by default when adding an erspan dev")
erspan_ver is initialized to 1 even for ip6gre or ip6gretap
Fix the issue moving erspan_ver initialization in a dedicated routine

Fixes: c706863bc8 ("net: ip6_gre: always reports o_key to userspace")
