[dpdk-dev] [PATCH 2/3] eal: increase scope of eal_thread_set_affinity

[Bruce Richardson <bruce.richardson@intel.com>]

This patch changes eal_thread_set_affinity to the EAL-local function
rte_eal_thread_set_affinity. This will allow us to use the function
anywhere else in the EAL, while not having it part of the official APIs
