From: Takashi Iwai <tiwai@xxxxxxx> commit abbff41b6932cde359589fd51f4024b7c85f366b upstream. This reverts commit c2d188e137e77294323132a760a4608321a36a70. Although it's fine to filter the invalid UMP groups at the first probe time, this will become a problem when UMP groups are updated and (re-)activated. Then there is no way to re-add the substreams properly for the legacy rawmidi, and the new active groups will be still invisible. So let's revert the change. This will move back to showing the full 16 groups, but it's better than forever lost.
