[dpdk-dev] [PATCH 06/13] app/flow-perf: fix memory leak from RSS action

[Wisam Jaddo <wisamm@mellanox.com>]

Currently, each call for add_rss_action will allocate
extra memory for rss_data, which will reflect bad results
on memory consumption for all flows, and will leads into
memory leak.

In this fix, it will check if it's allocated before
reallocating it.
