Martin Schwenke c1e8ea08e3 Clean up warnings: log some unchecked return codes from function calls ...

In a few places functions are called, the return code is assigned into
a variable but it is not checked.  This generates a compiler warning
like this:

  warning: variable ‘ret’ set but not used [-Wunused-but-set-variable]

Instead we remove the warning by checking the return code variable and
log a warning at DEBUG level if the return code indicates an error.
The justification is that there may have been a future intent to check
the return code but it hasn't been important enough to follow-up.  If
it matters, it will be logged for easy debugging.
