drivers/usbdev/cdcecm.c: fix cdcecm netdev can not enter running state
When the setinterface interface is called, it indicates that the underlying
USB link has been successfully established. At this point, the status of the
network card needs to be updated to RUNNING by calling the netdev_carrier_on
interface. It is similar to the logic after a Wi-Fi network card is
connected to a hotspot. Otherwise, an incorrect network card status may
cause packets to fail to be successfully sent.
