[libvirt] [PATCH 1/3] Use virGetLastErrorMessage to avoid Coverity message

[John Ferlan]

Both instances use VIR_WARN() to print the error from a failed
virDBusGetSystemBus() call.  Rather than use the virGetLastError
and need to check for valid return err pointer, just use the
virGetLastErrorMessage.
