NET: cdc-phonet, fix stop-queue handling

Currently there is a warning emitted by the cdc-phonet driver:
WARNING: at include/linux/netdevice.h:1557 usbpn_probe+0x3bb/0x3f0 [cdc_phonet]()

netif_stop_queue() cannot be called before register_netdev()

So remove netif_stop_queue from the probe funtction to avoid that.
