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)".
