From: Alvin Zhang <alvinx.zhang@intel.com>

Since the patch '1848b117' has set the value of key in 'struct
rte_flow_action_rss' to NULL, the PMD cannot get the RSS key now.

This patch sets offset and size of the key pointer as the first
parameter of the token 'key' and copies the start address of the
'HEX' data to the location specified by the first parameter of
the token.

Fixes: 1848b117cca1 ("app/testpmd: fix RSS key for flow API RSS rule")
