Roland Hieber 194b26536b osc: fix crashes related to field eventresponder being nil
I'm still getting some crashes after issue #3210 was fixed in commit
5beb230690. 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]	  [C]: in ?
    [osc]	  [C]: in ?
    [osc] Lua error: @osc.lua:2074: attempt to index field 'eventresponder' (a nil value)

Note that the location is different from where issue #3210 happens.
