usbnet:cdc-phonet: remove usb_get/put_dev in .probe and .disconnect
usb_device is parent device of usb_interface in the view of driver model, so its reference count is always held during .probe/.disconnect of usb_interface instance. This patch just removes the unnecessay usb_get/put_dev. Signed-off-by: Ming Lei <tom.leiming@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
