ALSA: seq: Check UMP support for midi_version change
commit 8765429279e7d3d68d39ace5f84af2815174bb1e 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.
