Subject: [PATCH] service: fix build with gcc 4.9
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

[ upstream commit ca13673513b656e632d5b348de2aa448b55ba9de ]

Some compilers detect this error:

    error: ‘ids[0]’ may be used uninitialized in this function
    ret = rte_service_map_lcore_set(i, ids[lcore_iter], 1);

It can be reproduced very easily on Fedora 21 with
gcc-4.9.2-6.fc21.x86_64.

Fixes: 21698354c832 ("service: introduce service cores concept")
