Fix Linus' bug in rh #134886

	* src/nm-device-802-3-ethernet.c
		- (constructor): request initial carrier state

	* src/nm-netlink-monitor.c
		- (nm_netlink_monitor_request_status): schedule emission of carrier
			signals after refilling the link cache.  Because the refill is a 
			synchronous operation, the normal message hander won't get called
			since libnl has already consumed the messages.
		- (deferred_emit_carrier_state): emit carrier states from an idle handler
