Report incorrect CPU model blockers in domain capabilities.

How reproducible is this bug?:

100%

Steps to reproduce

1. Execute the below shell script to compare CPU model blockers in domain capabilities  with qemu.

   un_usable_model=$(virsh domcapabilities --xpath "//model[@usable='no']/text()")
   all_model_pass="True"
   for model in $un_usable_model;do
       lacked_feature=()
       domcap_blocked_feature=$(virsh domcapabilities --xpath "//blockers[@model='$model']//feature"|awk -F '"' '{ print $2 }'| tr '\n' ' ')
       qemu_feature=($(diff <(virsh qemu-monitor-command 3 "{\"execute\":\"query-cpu-model-expansion\",\"arguments\":{\"type\":\"static\", \"model\":{\"name\":\"$model\"}}}" | jq ".return.model.props") \
                            <(virsh qemu-monitor-command 3 "{\"execute\":\"query-cpu-model-expansion\",\"arguments\":{\"type\":\"static\", \"model\":{\"name\":\"host\"}}}" | jq ".return.model.props") \
                          | grep '^<' | grep true | awk -F '"' '{print $2}' | tr '\n' ' '))
   
      for feature in "${qemu_feature[@]}"; do
      if echo "$domcap_blocked_feature" | grep -q "$feature"; then
          continue
      else
          lacked_feature+=($feature)
      fi
      done
   
      if [ "${#lacked_feature[@]}" -ne 0 ]; then
          echo -e "****Model name:$model blocked feature is lacking in qemu qmp,but not lacking in the virsh domcap:${lacked_feature[@]}\n"
          all_model_pass="False"
      fi
   done
   
      if [ "$all_model_pass" == "True" ];then
          echo "Checking the current host virsh domcap blocker lacked feature PASS"
      fi un_usable_model=$(virsh domcapabilities --xpath "//model[@usable='no']/text()")
   all_model_pass="True"
   for model in $un_usable_model;do
       lacked_feature=()
       domcap_blocked_feature=$(virsh domcapabilities --xpath "//blockers[@model='$model']//feature"|awk -F '"' '{ print $2 }'| tr '\n' ' ')
       qemu_feature=($(diff <(virsh qemu-monitor-command 3 "{\"execute\":\"query-cpu-model-expansion\",\"arguments\":{\"type\":\"static\", \"model\":{\"name\":\"$model\"}}}" | jq ".return.model.props") \

                          | grep '^<' | grep true | awk -F '"' '{print $2}' | tr '\n' ' '))
   
      for feature in "${qemu_feature[@]}"; do
      if echo "$domcap_blocked_feature" | grep -q "$feature"; then
          continue
      else
          lacked_feature+=($feature)
      fi
      done
   
      if [ "${#lacked_feature[@]}" -ne 0 ]; then
          echo -e "****Model name:$model blocked feature is lacking in qemu qmp,but not lacking in the virsh domcap:${lacked_feature[@]}\n"
          all_model_pass="False"
      fi
   done
   
      if [ "$all_model_pass" == "True" ];then
          echo "Checking the current host virsh domcap blocker lacked feature PASS"
