leds: trigger: netdev: Recheck NETDEV_LED_MODE_LINKUP on dev rename 

Dev can be renamed also while up for supported device. We currently
wrongly clear the NETDEV_LED_MODE_LINKUP flag on NETDEV_CHANGENAME
event.

Fix this by rechecking if the carrier is ok on NETDEV_CHANGENAME and
correctly set the NETDEV_LED_MODE_LINKUP bit.
