[ALSA] Fix open handling

USB USX2Y
Return -EBUSY from snd_usX2Y_usbpcm_open(), if the associated hwdep
device is not opened.

It now works as originally intended. Had forgotten a pair of parenthesis.

  It provides the alsa kernel half of the usx2y-alsa-jack driver pair.
  The pair uses a hardware dependant alsa-device for mmaped pcm transport.
  Advantage achieved:
-         The usb_hcd places reads/writes pcm data into dma-memory.
+         The usb_hc moves pcm data from/into memory via DMA.
          That memory is mmaped by jack's usx2y driver.
          Jack's usx2y driver is the first/last to read/write pcm data.
          Read/write is a combination of power of 2 period shaping and
