[libvirt] [PATCH]qemu: virDomainControllerFind may return 0 if controller found



From: Chen Hanxiao <chenhanxiao cn fujitsu com>

The return value of virDomainControllerFind >=0 means that
the specific controller was found.
But some functions invoke it and treat 0 as not found.
This patch fix these incorrect invocation.
