    grain_table.c: improve fscanf checks

    Replace `!fscanf()` with a check on the returned count as `fscanf` may
    also return `EOF.

    Fixes some clang-19 static analysis warnings of the form:

    ```
    File position of the stream might be 'indeterminate' after a failed
    operation. Can cause undefined behavior
    ```
