USB-Serial: Fix error handling of usb_wwan This fixes an issue where the bulk-in urb used for incoming data transfer is not resubmitted if the packet recieved contains an error status. This results in the driver locking until the port is closed and re-opened. Tested on a custom board with a Cinterion GSM module.
