[dpdk-dev] [PATCH 1/2] timer: clarify subsystem_init return value

[Michal Krawczyk <mk@semihalf.com>]

From: Stanislaw Kardach <kda@semihalf.com>

rte_timer_subsystem_init() may return -EALREADY if it has been already
initialized. Therefore put explicitly into doxygen that this is not a
failure for the application.
