ALSA: rawmidi: fix the get next midi device ioctl
If we pass in a device which is higher than SNDRV_RAWMIDI_DEVICES then
the "next device" should be -1. This function just returns device + 1.
But the main thing is that "device + 1" can lead to a (harmless) integer
overflow and that annoys static analysis tools.
