ntdll: Always set a valid SUB_Q_HEADER AudioStatus for CD-ROMs.

[Michael Stefaniuc]

Broken CD-ROMs aka "copy protected" by not following the standard will
give an invalid CD sub-channel audio status; Linux happily passes that
on to the application.

---
The educational game at hand requires the CD to run. It is a mixed mode CD with
audio tracks but trying to access them makes the DVD drive blink wildly and
basically lock up until the CD is ejected.

The struct cdrom_subchnl.cdsc_audiostatus returned is 0x0A which is invalid:
    95.846:0024:trace:cdrom:CDROM_ReadQChannel status=0A !
All valid audio status except AUDIO_STATUS_NOT_SUPPORTED will make the
program continue. The program is not happy with uninitialized memory nor
the invalid status 0x0A.
