iio: humidity: ens210: remove compiler warning workaround

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().
