[libvirt] [PATCH 2/2] qemu: monitor: Decrease logging verbosity

[Peter Krempa]

The PROBE macro used in qemuMonitorIOProcess and the VIR_DEBUG message
in qemuMonitorJSONIOProcess create a lot of logging churn when debug
logging is enabled during monitor communication.

The messages logged from the PROBE macro are rather useless since they
are reporting the partial state of receiving the reply from qemu. The
actuall full reply is still logged in qemuMonitorJSONIOProcessLine once
the full message is received.
