We should allow resetting and freeing qemuDomainJobObj even if 'cb' attribute is not set. This is theoretical for now, but the attribute must not be always set in the future, so early return would create memory leaks. It is sufficient to check if 'cb' exists before dereferencing it in qemuDomainObjClearJob() and also qemuDomainObjResetAsyncJob() as the latter is called from the former.
