[dpdk-dev] [PATCH v2] app/testpmd: fix DCB configuration

[Jie Wang <jie1x.wang@intel.com>]

When set port DCB mode enabled, it should remove RSS HASH offload
before reconfiguring the device and queues.

Because port multi-queue mode is changed from RSS to DCB.

Fixes: 2a977b891f99 ("app/testpmd: fix DCB configuration")
