fix unconditional note resolution during DiskReader::realtime_locate()

When looping, we do not want to resolve notes at the end of the loop via ::realtime_locate() -
::get_midi_playback() has already taken care of this. But when not looping, we need this. So,
add an argument to tell all interested parties whether the locate is for a loop end or not
