[libvirt] [PATCH] qemu_monitor_json.c: avoid an unconditional leak

[Jim Meyering]

Calling virJSONValueFree does not free the memory allocated via this:

    cmd = qemuMonitorJSONMakeCommand("drive_add",
                                     "s:pci_addr", dev,
                                     "s:opts", drivestr,
                                     NULL);

so I added the VIR_FREE:
