osc: fix crashes related to field eventresponder being nil
I'm still getting some crashes after issue #3210 was fixed in commit 5beb2306904b4437b5acf136b02aeaa073c351c7. It's hard to reproduce those crashes, they happen maybe once a month, so I guess it could be a race condition. But in any case, I don't see anything wrong in applying some defensive programming here. For reference, here is what was happening on 0.23.0-1 from Debian testing: Playing: ytdl://usL5CeP_row (+) Video --vid=1 (*) (h264) (+) Audio --aid=1 --alang=und (*) (aac) [osc] [osc] stack traceback: [osc] @osc.lua:2074: in function 'process_event' [osc] @osc.lua:2246: in function 'cb' [osc] mp.defaults:107: in function 'fn' [osc] mp.defaults:60: in function 'handler' [osc] mp.defaults:339: in function 'handler' [osc] mp.defaults:448: in function 'call_event_handlers' [osc] mp.defaults:485: in function 'dispatch_events' [osc] mp.defaults:441: in function <mp.defaults:440> [osc] [C]: in ?
