USB-Serial: Fix error handling of usb_wwan commit 6c1ee66a0b2bdbd64c078fba684d640cf2fd38a9 upstream. 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.
