[PATCH 2/2] app/test: fix bonding RSS test when disable RSS

[Dongdong Liu <liudongdong3@huawei.com>]

From: Huisong Li <lihuisong@huawei.com>

The "test_rss_lazy" test is used for testing bonding RSS functions
when bonded port disable RSS. Currently, this test case can update
RSS functions of bonded and slave port if bonded port turns off RSS.
It is unreasonable and has been adjusted to be non-updateable in
following patch:
"93e1ea6dfa99 ethdev: fix RSS update when RSS is disabled"

So this patch fixes this test code.

Fixes: 43b630244e7e ("app/test: add dynamic bonding RSS configuration")
