[PATCH 1/2] config.c: drop local variable

[Stefan Beller <sbeller@google.com>]

As `ret` is not used for anything except determining an early return,
we don't need a variable for that. Drop it.

While reading config code, I found 2 nits. Both improve readability,
no bugfix or feature.

As it is generally discouraged to have cleanup patch churn,
I checked master..pu to see any possible topics in flight conflicting
on config.c or submodule-config.c and there is nothing close by.

Thanks,
Stefan
