1. Fix: Lock interest_mutex_ When interest_ Modified in ctlEx …

   EventMethEpollEquivImpl::ctlEx now locks interest_mutex_ when
   performing its add/mod/del actions.
   
   Previously, the interest_mutex_ lock was released before these
   add/mod/del actions were performed. This was confirmed to occasionally
   cause a "use after free" in findEmEventInAnInterestSet (called out of
   getReadyEmEvents) in another thread. It might also result in
   corruption of the interest_ std::set.
