The wording in this commit message is a little confusing, what is
the exact lock conflict? 

After your patch, there are no longer any callers for __rte_timer_stop()
with the local_is_locked flag. Please resubmit and remove all the
the local_is_locked from __rte_timer_stop().

It looks like the test suite for rte_timer is not exercising all
the exposed API's. That's a problem
