bug:
 - add midi track
 - add additional midi port
 - remove additional midi port
 - press play
 -> crash

because..

ARDOUR::MidiTrack::roll's route_buffer still has 2 midi-channels. This is
because processor_max_streams was not updated (no plugins added/removed)
fill_buffers_with_input() eventually asserts when trying to get the 2nd
(nonexistant) midi port via ARDOUR::PortSet::nth_midi_port() in
 ARDOUR::PortSet::port().
