[libvirt] [PATCH] testNodeDeviceMockCreateVport: Don't call public APIs
This function is calling public APIs (virNodeDeviceLookupByName
etc.). That requires the driver lock to be unlocked and locked
again. If we, however, replace the public APIs calls with the
internal calls (that public APIs call anyway), we can drop the
lock/unlock exercise.
