[dpdk-stable] [PATCH] eal: fix wrong config file path

[Jianfeng Tan <jianfeng.tan@intel.com>]

When primary process is booted with --file-prefix option, the API,
rte_eal_primary_proc_alive(), uses a wrong config file path to
check if primary process is alive.

Fix it by calling helper function to get config file path.

Fixes: dd3e00138d74 ("eal: check if primary process is alive")
