Fix task_wait_event() in zinger runtime so that checking for events fired is done with interrupts disabled to avoid getting an interrupt that sets an event right after checking for that event. BUG=none BRANCH=samus TEST=load on zinger and plug/unplug ~10 times and see successful negotiations without any communication errors. note that without this CL, under certain circumstances, zinger fails to respond with goodCRC at the right time because the RX interrupt sets the event after task_wait_event() has already checked it.
