Subject: [PATCH 24/26] iotests/229: Use blkdebug to inject an error

O-Subject: [RHEL-AV-8.2.1 qemu-kvm PATCH v2 09/11] iotests/229: Use blkdebug to inject an error
Bugzilla: 1778593

229 relies on the mirror running into an I/O error when the target is
smaller than the source. After changing mirror to catch this condition
while starting the job, this test case won't get a job that is paused
for an I/O error any more. Use blkdebug instead to inject an error.
