ovs/gre: fix rtnl notifications on iface deletion
The function gretap_fb_dev_create() (only used by ovs) never calls rtnl_configure_link(). The consequence is that dev->rtnl_link_state is never set to RTNL_LINK_INITIALIZED. During the deletion phase, the function rollback_registered_many() sends a RTM_DELLINK only if dev->rtnl_link_state is set to RTNL_LINK_INITIALIZED.
