The loop cleaning up flowdir resources was using SLIST_FOREACH
but the inner loop would call rte_free. Found by building with
address sanitizer undefined check.
Also remove needless initialization, and null check.

The cleanup loop would deference the dpio_dev after freeing.
Use TAILQ_FOREACH_SAFE to fix that.
Found by building with sanitizer undefined flag.

The cleanup loop would deference the dpio_dev after freeing.
Use TAILQ_FOREACH_SAFE to fix that.
Found by building with sanitizer undefined flag.

The filter cleanup loop was using STAILQ_FOREACH and rte_free
and would dereference the filter after free.
