openvswitch: restore OVS_FLOW_CMD_NEW notifications
Since commit fb5d1e9e127a ("openvswitch: Build flow cmd netlink reply only if needed."),
the new flows are not notified to the listeners of OVS_FLOW_MCGROUP.
This commit fixes the problem by using the genl function, ie
genl_has_listerners() instead of netlink_has_listeners().
