Description of problem:
Can not get a valid ip after hot plug/unplug rtl8139 nic on q35 machines. And when hot unplug the device, it will not disappear from the device manager, useing "scan for hardware changes", the device will disappear normally.

Version-Release number of selected component (if applicable):
qemu-kvm-5.2.0-1.module+el8.4.0+9091+650b220a.x86_64
kernel-4.18.0-262.el8.x86_64

2.Hot unplug device
{'execute': 'device_del', 'arguments': {'id': 'id3hq3Te'}}
{'execute': 'netdev_del', 'arguments': {'id': 'idvc6ke6'}}

3.Check the device status, it does not disappear from the device manager.


Actual results:
Hot unplug rtl8139 nic, it does not disappear from the device manager.

Expected results:
After hot unplug device,it will disappear from the device manager

Additional info:
RHEL guest works well,
