CD-ROM Forward/Backward command returns INT2 instead of INT3 and does not seek.

[Rhys-Baker]

Describe the bug

Issuing the Forward or Backward command to the CD-ROM drive should result in an INT3(stat) but it returns INT2(stat). It also does not fast-forward or rewind the currently playing audio.

Expected behavior

Issuing a Forward/Backward command to the CD-ROM drive should raise an INT3(stat) and begin to fast-forward/rewind the currently playing audio.

Steps to reproduce the bug

Issue a CD-ROM command 0x04 or 0x05 (forward/backward)
Listen for INT2 and INT3.
INT2 will be raised, instead of INT3
