Takashi Iwai 568be8aaf8 ALSA: usb-audio: Fix NULL dererence at error path 
At an error path to release URB buffers and contexts, the driver might
hit a NULL dererence for u->urb pointer, when u->buffer_size has been
already set but the actual URB allocation failed.

Fix it by adding the NULL check of urb.  Also, make sure that
buffer_size is cleared after the error path or the close.
