ALSA: rawmidi: Skip UMP devices at SNDRV_CTL_IOCTL_RAWMIDI_NEXT_DEVICE

Browse source

Applications may look for rawmidi devices with the ioctl
SNDRV_CTL_IOCTL_RAWMIDI_NEXT_DEVICE.  Returning a UMP device from this
ioctl may confuse the existing applications that support only the
legacy rawmidi.

This patch changes the code to skip the UMP devices from the lookup
for avoiding the confusion, and introduces a new ioctl to look for the
UMP devices instead.

Along with this change, bump the CTL protocol version to 2.0.9.
