test/bonding: fix uninitialized RSS configuration

[ upstream commit fb662d632d80fe74333e39155354814c98920ba9 ]

Driver reported RSS key size checked against user configuration in
ethdev layer, need to initialize "struct rte_eth_rss_conf" before
configuring RSS. Otherwise, an error will occur.

Bugzilla ID: 1308
Fixes: 43b6302 ("app/test: add dynamic bonding RSS configuration")
Fixes: bae3cfa520a7 ("ethdev: clarify RSS related fields usage")
