If there's a parsing error we'll already report it via the usual fsck report() function (or not, if the user has asked to skip this object or warning type). The error message from the config parser just adds confusion. Let's suppress it.
Note that we didn't test this case at all, so I've added coverage in t7415. We may end up toning down or removing this fsck check in the future. So take this test as checking what happens now with a focus on stderr, and not any ironclad guarantee that we must detect and report parse failures in the future.
