How reproducible:
1/5

Steps to Reproduce:
1. boot guest with below cmd lines.
/usr/libexec/qemu-kvm \
-name 'avocado-vt-vm1' \
-sandbox on \
-machine q35 \
-device pcie-root-port,id=pcie-root-port-0,multifunction=on,bus=pcie.0,addr=0x1,chassis=1 \
-device pcie-pci-bridge,id=pcie-pci-bridge-0,addr=0x0,bus=pcie-root-port-0 \

-device pcie-root-port,id=pcie-root-port-3,port=0x3,addr=0x1.0x3,bus=pcie.0,chassis=4 \

2. hotplug blk device
{"execute": "blockdev-add", "arguments": {"node-name": "file_stg0", "driver": "file", "aio": "threads", "filename": "/home/kvm_autotest_root/images/storage0.raw", "cache": {"direct": true, "no-flush": false}}, "id": "ZODSKhzq"}
{"execute": "blockdev-add", "arguments": {"node-name": "drive_stg0", "driver": "raw", "cache":

, "file": "file_stg0"}, "id": "PDBqM4ab"}
{"execute": "device_add", "arguments":

, "id": "AfUx0F55"}

3.format disk in disk manager

4.hotunplug blk device
{'execute': 'device_del', 'arguments':

, 'id': 'w4Tj7zKN'}
{'execute': 'blockdev-del', 'arguments':

, 'id': 'inkmmsdp'}
{'execute': 'blockdev-del', 'arguments':

, 'id': 'WqOdPb0n'}

4.repeate step 2 and 4

5.send command :'wmic logicaldisk get drivetype,name,description & wmic diskdrive list brief /format:list' to check disk info

Actual results:
After step5,disk still display in disk manager,but can not get its info.

Expected results:
data disk should not display in disk manager after hotunplug.
