There is a confusing mix of ipgre and gretap functions with some
needed for gretap still having ipgre_ prefixes.  This time though
I think I got the rest of the unused ipgre code.

Fixes: d5822f428814 ("gre: Remove dead ipgre code")

Hi.

This broke build with kernel 4.15.18:
https://travis-ci.org/openvswitch/ovs/jobs/605766364

datapath/linux/ip_gre.c: In function ‘ipgre_tunnel_init’:
datapath/linux/ip_gre.c:940:22: error: ‘ipgre_header_ops’ undeclared (first use in this function)
    dev->header_ops = &ipgre_header_ops;
                       ^
datapath/linux/ip_gre.c:940:22: note: each undeclared identifier is reported only once for each function it appears in
datapath/linux/ip_gre.c: At top level:
datapath/linux/ip_gre.c:925:12: warning: ‘ipgre_tunnel_init’ defined but not used [-Wunused-function]
  static int ipgre_tunnel_init(struct net_device *dev)
             ^
datapath/linux/ip_gre.c:946:20: warning: ‘ipgre_xmit’ defined but not used [-Wunused-function]
  static netdev_tx_t ipgre_xmit(struct sk_buff *skb,
                     ^

Best regards, Ilya Maximets.

Thanks Ilya, I'm working on fixing it.  I must have pushed a 'between' 
patch in my own travis test.
