Well, every other user of the function also looks like

	vports = lpfc_create_vport_work_array(phba);
	if (vports != NULL) {
		do_something(vports);
	}
	lpfc_destroy_vport_work_array(phba, vports);

and lpfc_destroy_vport_work_array() does nothing if its argument is NULL.

I still think my patch is the correct fix for the warning.
