  datapath: Check if gre kernel module is loaded

Before attempting to add a gre tunnel to OVS via the vport gre
kernel interface make sure that the openvswitch kernel module has
been able to grab the gre protocol entry point.  If OVS does not
own the gre protocol then report address family not supported.
