ALSA: usx2y: Stop clearing urb->hcpriv before submission

Browse Source 
This is managed by USB core and drivers aren't expected to touch it.

It should only be not NULL on a submitted URB, in which case clearing
defeats the "submitted while active" sanity check in usb_submit_urb()
and may crash the HCD handling the URB and panic the kernel.
