Fix zinger and keyborg to use correct event mask when timing out from task_wait_event(): TASK_EVENT_TIMER. On zinger, move storing the last event to after enabling interrupts. This gives an opportunity to interrupt handler to set the wake event. BUG=chrome-os-partner:30135 BRANCH=none TEST=load on zinger, and test PD communication with samus. notably tested sending rw_hash vdm from samus, which is known to cause zinger to retry the following ping transmit. The retry on the ping transmit uses task_wait_event(), and without this fix we were getting false wake events that had been stored up from the last rx received event. with this fix, the retry mechanism works.
