[PATCH 6/6] winmm: Audio drivers unconditionally invoke DriverCallback.

[Joerg-Cyril.Hoehle at t-systems.com]

Hi,

MSDN says about some conformance tests: "When midiOutOpen is called
with dwCallback equal to NULL and dwFlags equal to CALLBACK_NULL, the
driver must still call DriverCallback.  This is verified by ensuring
that the MHDR_DONE flag is set in the dwFlags field of the lpMidiOutHdr
parameter to midiOutLongMsg after a SysEx message is sent."

I never understood the second sentence (does DriverCallback set
MHDR_DONE?) but let's always invoke DriverCallback.

Regards,
 Jörg Höhle
