USB: serial: clean up read processing in generic driver
Always process and flush read urb, but only resubmit when not throttled.
The new tty-layer supply plenty of slack so there is really no need to
cache and delay processing of a single urb while throttled.
Note that unthrottle now submits using GFP_KERNEL as we are not in
atomic context (so there is no need to save irq state either).
Note also that the process_read_urb function could be added to
usb_serial_driver should any driver need to do any device specific
processing.
