ALSA: seq: Check UMP support for midi_version change
commit 87654292 upstream. When the kernel is built without UMP support but a user-space app requires the midi_version > 0, the kernel should return an error. Otherwise user-space assumes as if it were possible to deal, eventually hitting serious errors later.
