Monasca-agent libvirt.py check has missing parameter in _inspect_state method call

[Laszlo Hegedus]

I have tried out the libvirt check from latest master and observed the following lines repeating in collector log:

2016-07-11 05:06:46 EDT | ERROR | collector | monasca_agent.collector.checks.check.libvirt(check.py:248) | Check 'libvirt' instance #0 failed
Traceback (most recent call last):
  File "/root/monasca-venv/lib/python2.7/site-packages/monasca_agent/collector/checks/check.py", line 246, in run
    self.check(instance)
  File "/root/monasca-venv/lib/python2.7/site-packages/monasca_agent/common/../collector/checks_d/libvirt.py", line 643, in check
    dims_customer, dims_operations) != 0:
TypeError: _inspect_state() takes exactly 7 arguments (6 given)

The _inspec_state call in check is missing the inst_name parameter.
