vsprintf: Avoid confusion between invalid address and value
We are able to detect invalid values handled by %p[iI] printk specifier. The current error message is "invalid address". It might cause confusion against "(efault)" reported by the generic valid_pointer_address() check. Let's unify the style and use the more appropriate error code description "(einval)".
