Fix regression issue in the USB file system interface. - Use cdev_privdata pointer as indicator of correct file handle. - Remove redundant FIFO opened flags. Don't send ZLP at close for ulpt and uscanner devices as this causes some models to stop working. This reverts back to the USB1 behaviour. Submitted by: Hans Petter Selasky
