[v2 1/1] app/test: remove useless calls to rte_bitmap_free

[Ariel Otilibili]

* rte_bitmap_free is only useful for its return value
* and its return value is not used.

```
$ < lib/eal/include/rte_bitmap.h sed -ne '/bitmap_free/,/^}/p'

rte_bitmap_free(struct rte_bitmap *bmp)
{
        /* Check input arguments */
        if (bmp == NULL) {
                return -1;
        }

        return 0;
}
```
