pc: Improve error message when die-id is omitted

Browse source 
The error message when die-id is omitted doesn't make sense:

  $ qemu-system-x86_64 -smp 1,sockets=6,maxcpus=6 \
    -device qemu64-x86_64-cpu,socket-id=1,core-id=0,thread-id=0
  qemu-system-x86_64: -device qemu64-x86_64-cpu,socket-id=1,core-id=0,thread-id=0: \
    Invalid CPU die-id: 4294967295 must be in range 0:0

Fix it, so it will now read:

  qemu-system-x86_64: -device qemu64-x86_64-cpu,socket-id=1,core-id=0,thread-id=0: \
    CPU die-id is not set
