[media] media: vb2: fix allocation failure check

Browse source

__vb2_queue_alloc function returns the number of successfully allocated
buffers. There is no point in checking if the returned value is negative.
If this function returns 0, videobuf2 should just return -ENOMEM to
userspace, because no driver can work without memory buffers.
