I'm really don't like the approach of adding 'bool reportError' flags to
internal functions as it doesn't scale. These flags end up creeping out
across more & more of the code base and different callers are going to
disagree about which errors should be ignored and which not. Having the
callers use virResetError is preferrable IMHO as it avoids polluting
countless internal functions with ill defined args.
