[libvirt] [PATCH] qemu: silence Coverity false positive

[Eric Blake]

Coverity complained that 4 out of 5 callers to virJSONValueObjectGetBoolean
checked for errors.  But we documented that we don't care in this case.

* src/qemu/qemu_monitor_json.c (qemuMonitorJSONGetBlockInfo): Use
ignore_value.

Pushing under the trivial rule.
