event: Only process if event_init has been run.

Browse Source 
Reported by @fourjay, a codepath that causes event_poll() to run before
event_init() will trigger a segfault as the events list will not have
been initialized. Exiting immediately from event_init() causes nvim to
hang, so just exit before running the events.

fixes #2339
