ac97: don't override the pci subsystem id
This patch removes the code lines which set the subsystem id for the
emulated ac97 card to 8086:0000. Due to the device id being zero the
subsystem id isn't vaild anyway. With the patch applied the sound card
gets the default qemu subsystem id (1af4:1100) instead.
[ v2: old & broken id is maintained for -M pc-$oldqemuversion ]
