now that usb_wait_task() is back, bring back recently reverted
changes: * use usb_ref_{incr,decr,wait}() to avoid detaching the driver while a process is still using the hardware. * don't add timeout(9)s if the device is detached. * add checks to see if the device has been detached before running ioctls, timeouts, and tasks. * use usb_wait_task() to wait for tasks to complete. ok damien@
