ip_gre: fix IFLA_MTU ignored on NEWLINK
It's safe to remove the setting of dev's needed_headroom and mtu in
__gre_tunnel_init, as discussed in [1], ip_tunnel_newlink can do it
properly.
Now Eric noticed that it could cover the mtu value set in do_setlink
when creating a ip_gre dev. It makes IFLA_MTU param not take effect.
So this patch is to remove them to make IFLA_MTU work, as in other
ipv4 tunnels.
