Takashi Iwai 121fadc0ca ALSA: usb-audio: Fix NULL dererence at error path 
commit 568be8aaf8a535f79c4db76cabe17b035aa2584d upstream.

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.
