    erspan: set erspan_ver to 1 by default when adding an erspan dev

    After erspan_ver is introudced, if erspan_ver is not set in iproute, its
    value will be left 0 by default. Since Commit 02f99df1875c ("erspan: fix
    invalid erspan version."), it has broken the traffic due to the version
    check in erspan_xmit if users are not aware of 'erspan_ver' param, like
    using an old version of iproute.

    To fix this compatibility problem, it sets erspan_ver to 1 by default
    when adding an erspan dev in erspan_setup. Note that we can't do it in
    ipgre_netlink_parms, as this function is also used by ipgre_changelink.
