commit 86cae503a4404e068a11285564a0ee3862d1570c
Author: Daniel P. Berrangé <berrange@redhat.com>

rpc: avoid crashing in pre-exec if no workers are present
    
    If max_workers is set to zero, then the worker thread pool won't be
    created, so when serializing state for pre-exec we must set various
    parameters to zero.
