Description of problem:
Vm failed to start on the target host but libvirt still keep the vm paused on the source host when do postcopy

Version-Release number of selected component (if applicable):
libvirt-8.5.0-5.el9.x86_64
qemu-kvm-7.0.0-11.el9.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Do postcopy with a low postcopy speed(leave time to cancel postcopy):

1. virsh migrate avocado-vt-vm1 qemu+ssh://*.com/system --live --p2p --verbose --bandwidth 10 --postcopy --timeout-postcopy --timeout 10 --postcopy-bandwidth 5

2.Open another terminal, change the ownership of vm's disk to 'root:root':
#chown root:root /var/lib/libvirt/images/nfs/ovmf.qcow2

3.The migration in step 1 failed because the guest can not run on the target host:
Migration: [ 1 %]error: internal error: unable to execute QEMU command 'cont': Could not open '/var/lib/libvirt/images/nfs/ovmf.qcow2': Permission denied

4.Check the guest status on both source and target:
source host:
#virsh list
Id Name State
-------------------------------
5 avocado-vt-vm1 paused

target host:
#virsh list
no output

5.Do migration again:

1. virsh migrate avocado-vt-vm1 qemu+ssh://*.com/system --live --p2p --verbose --bandwidth 10 --postcopy --timeout-postcopy --timeout 10 --postcopy-bandwidth 5
   error: Requested operation is not valid: another migration job is already running for domain 'avocado-vt-vm1'

Actual results:
Vm failed to start on the target host but libvirt still keep the vm paused on the source host when do postcopy

Expected results:
Libvirt should keep the vm on the source running if guest failed to start on the target host.
