Oliver Neukum 339f83612f usb: cdc-wdm: close race between read and workqueue 
wdm_read() cannot race with itself. However, in
service_outstanding_interrupt() it can race with the
workqueue, which can be triggered by error handling.

Hence we need to make sure that the WDM_RESPONDING
flag is not just only set but tested.
