USB: unkill cxacru atm driver

Browse Source 
it seems like you overdid it a bit in your quest to clean up the
use of urb->status. In this driver you read it the first thing, which
means that you are in a race against URB completion you'll
usually lose, returning -EINPROGRESS. This kills the driver.
