Takashi Iwai db737117e9 ALSA: usx2y: Fix potential NULL dereference 
commit 7686e3485253635c529cdd5f416fc640abaf076f upstream.

The error handling code in usX2Y_rate_set() may hit a potential NULL
dereference when an error occurs before allocating all us->urb[].
Add a proper NULL check for fixing the corner case.
