Subject: eal: fix errno on service cores init failure
X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=4ecda7f05293d76f07e313f1e778806ae792ed0c

eal: fix errno on service cores init failure

Currently, when rte_service_init() fails at initialization, we
see the following message:

  Cannot init EAL: Exec format error

This error code does describe the real issue. Instead, use the error
code returned by the function.

Fixes: e39824500825 ("service: initialize with EAL")
