Igor Mammedov 6970c5ff13 pc: make sure that plugged CPUs are of the same type 
heterogeneous cpus are not supported and hotplugging different
cpu model crashes QEMU:

  qemu-system-x86_64 -cpu qemu64 -smp 1,maxcpus=2
  (qemu) device_add host-x86_64-cpu,socket-id=1,core-id=0,thread-id=0,id=foo
  (qemu) info cpus
  error: failed to get MSR 0x38d
  qemu-system-x86_64: target/i386/kvm.c:2121: kvm_get_msrs: Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed.
  Aborted (core dumped)

Gracefully fail hotplug process in case of user mistake.
