[dts] test_plans/pmdrssreta: make RSS RETA test plan generic

[Rami Rosen]

Following a patch which was applied recently, the RSS RETA Test Suite
(tests/TestSuite_pmdrssreta.py) runs also on Huawei hinic PMD, and is
 no longer specific to Niantic PMD.
See: http://mails.dpdk.org/archives/dts/2019-April/005653.html
This patch fixes the RSS RETA test plan accordingly.
