[PATCH 4/4] [v2] winmm: Support TIME_MIDI position in MIDI stream.

[Akihiro Sagawa]

In v2,
Remove awkward goto statement, duplicate TIME_MS code fragment instead.
Andrew, as an alternative, do you prefer the following way?

---
redo:
 switch (lpMMT->wType) {
     :  :  :
   /* fall through to alternative format */
   case TIME_MS:
     lpMMT->u.ms = midistream_get_playing_position(lpMidiStrm);
     break;
   default:
     lpMMT->wType = TIME_MS;
     goto redo;
 }
