I'd write this as:

  if (def->resource->appid &&
      virDomainDefResourceAppidValidate() < 0)
      return -1;

so that this line doesn't have to be changed when something new is added
to this function. Moreover, you can have
virDomainDefResourceAppidValidate() to be NOP if appid == NULL and write
this check as:

  if (virDomainDefResourceAppidValidate() < 0)
    return -1;
