Command show-port should show RSS info (rss_key, len and rss_hf),
However, the information is showned only when rss_conf.rss_key is not
NULL. Since no memory is allocated for rss_conf.rss_key, rss_key
will always be NULL and the rss_info will never show. This patch
allocates memory for rss_conf.rss_key and makes it possible to show
RSS info.
Fixes: 8a37f37fc243 ("app/procinfo: add --show-port")
