fs-util: don't second guess openat_report_new() return values

If openat_report_new() fails, then 'made_file' will be false, as no file
was created, hence there's no need to skip the unlinkat() explicitly
early, given that we check for 'made_file' anyway in the error path. The
extra error code checks are hence entirely redundant.
