Rewrite IIO_CHAN_INFO_RAW case to avoid needing to add unreachable code to work around a compiler warning. When scoped_guard() was first introduced, compilers could not see when it returned unconditionally from inside the hidden for loop. This has since been fixed in the macro definition. So removing the `return -EINVAL` should be enough. Still, we can improve readability, decrease indentation and avoid the hidden for loop by rewriting the case without scoped_guard().
