[PATCH] app/testpmd: display RSS hash key of rte flow rule

[Dongdong Liu]

From: Huisong Li <lihuis...@huawei.com>

There are two ways to set RSS hash key with rte flow rule:
1. 'key_len' isn't zero and 'key' is NULL.
2. 'key_len' isn't zero and 'key' isn't NULL.
This patch adds displaying for the hash key of rte flow rule.
