Hans Verkuil 814e92b8ca [media] v4l2-ctrls.c: add NULL check ...

Check that the control whose events we want to delete is still there.

Normally this will always be the case, but I am not 100% certain if
there aren't any corner cases when a device is forcibly unbound.

In any case, this will satisfy static checkers and simply make it more
robust.
