ovs/geneve: fix rtnl notifications on iface deletion

The function geneve_dev_create_fb() (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. Fixes: e305ac6 ("geneve: Add support to collect tunnel metadata.")
