genetlink: add and use genl_set_err()
Add a static inline to generic netlink to wrap netlink_set_err() to make it easier to use here - use it in openvswitch (the only generic netlink user of netlink_set_err()). Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
