crypto: qat - move returns to default case

Make use of the default statements by changing the pattern:
	switch(condition) {
	case COND_A:
	...
		break;
	case COND_b:
	...
		break;
	}
	return ret;

in

	switch(condition) {
	case COND_A:
	...
		break;
	case COND_b:
	...
		break;
	default:
		return ret;
	}
