[libvirt] [PATCH] Fix locking issue in testVolumeLookupByPath

[Cole Robinson <crobinso redhat com>]

The attached patch fixes a locking issue in the test driver,
specifically testStorageVolumeLookupByPath. We were only unlocking the
pool object if it was running. This fixed a deadlock I was seeing while
adding some new tests to virtinst's test framework.

Thanks,
Cole
