A crash occurs in the examples/performance-thread/l3fwd-thread when it calls
into rte_timer_manage() from the LThread library it utilizes.  This happens
because the application omitted a call to rte_timer_subsystem_init(), which
leaves a pointer set to null in the timer library.  This pointer is
dereferenced in a check for validity of a timer data object, resulting in
the segfault.  This series fixes the validity check in the timer library,
and adds the missing call to rte_timer_subsystem_init in the application.
