[dpdk-dev] [PATCH] eal: fix memleak on mp request error handler

[g***@vip.163.com]

From: Gao Feng <***@tencent.com>

When rte_eal_alarm_set failed, need to free the bundle mem in the
error handler of handle_primary_request and handle_secondary_request.

The incriminated commit did relax the condition to catch all sections
but dropped the + removal which can trigger false detection of the
special EXPERIMENTAL section when adding symbols and the section in the
same patch.

Sorry for the noise. Please ignore this reply.

It is caused by wrong command.
