usb: wwan: Fix RX data corruption issue

The received data is pushed to TTY in global workqueue context.
The work is scheduled from URB completion handler and TTY unthrottle
callback.  The global workqueue does not guarantee non-reentrance.
The data is getting corrupted when work is run simultaneously on
multiple processors.  Use non-reentrant version of global workqueue.
