timer: remove unnecessary list insertion

Browse Source 
When timer_set_running_state() fails in rte_timer_manage(),
the failed timer is put back on pending-list.
In this case, another core tries to reset or stop the timer.
It does not need to be on pending-list.

Fixes: a4b7a5a45cf5 ("timer: fix race condition")
