Colin Ian King d4f0bf4525 usbip: vudc: fix null pointer dereference on udc->lock commit `df3334c223` upstream. Currently the driver attempts to spin lock on udc->lock before a NULL pointer check is performed on udc, hence there is a potential null pointer dereference on udc->lock. Fix this by moving the null check on udc before the lock occurs.
