'flag' initialized to '0' but it is overwritten later, initial
assignment can be removed.

Fixes: 0101a0ec6217 ("app/procinfo: add --show-mempool")

Hi Ferruh,

Thanks for the update

Checking the current code base it makes more sense to move the code inside `if` condition check. Sample code shared below

```
-	uint64_t flags = 0;

	snprintf(bdr_str, MAX_STRING_LEN, " show - MEMPOOL ");
	STATS_BDR_STR(10, bdr_str);

	if (name != NULL) {
		struct rte_mempool *ptr = rte_mempool_lookup(name);
		if (ptr != NULL) {
			struct rte_mempool_ops *ops;

+			unsigned int flags = ptr->flags;
			ops = rte_mempool_get_ops(ptr->ops_index);
```

But it is ok

I think both are OK, this is trivial, let me send a quick v2.
