      Description of problem:
      Windows 2022 gets BSOD 'PROCESSOR_START_TIMEOUT (1df)' after hotplugging max cores with with_hugepages sometimes

      Version-Release number of selected component (if applicable):
      Host:
      5.14.0-268.el9.x86_64
      qemu-kvm-7.2.0-9.el9.x86_64
      edk2-ovmf-20221207gitfff6d81270b5-6.el9.noarch
      libvirt-9.0.0-6.el9.x86_64
      dell-per750-25.lab.eng.pek2.redhat.com (Icelake)
      swtpm-0.8.0-1.el9.x86_64
      Guest: Win2022

      How reproducible:
      1/6

      Steps to Reproduce:
      1. Set hugepages on host:

      1. mount -t hugetlbfs -o pagesize=2048K none /mnt/kvm_hugepage

      2. Boot windows 2022 vm with ' -smp 1,maxcpus=48,cores=48,threads=1,dies=1,sockets=1', Full qemu command line [1]

      3. hotplug max cores:

      {'execute': 'device_add', 'arguments': OrderedDict([('id', 'vcpu47'), ('driver', 'Icelake-Server-x86_64-cpu'), ('socket-id', 0), ('die-id', 0), ('core-id', 47), ('thread-id', 0)]), 'id': 'kKNeBTZi'}

      4. Check guest status.

      Actual results:
      Guest gets BSOD 'PROCESSOR_START_TIMEOUT (1df)'

      Expected results:
      Guest works well without any error.
