Public bug reported:

Version: OpenStack Liberty

If the compute manager _shutdown_instance method's call to
_try_deallocate_network at [1] fails, the exception from the virt driver
destroy, which is the real root cause of the shutdown / delete instance
failure is lost.

This makes it harder to debug why the virt driver destroy method failed.
