Hans Verkuil f45f3f753b media: v4l2-ctrls.c/uvc: zero v4l2_event 
Control events can leak kernel memory since they do not fully zero the
event. The same code is present in both v4l2-ctrls.c and uvc_ctrl.c, so
fix both.

It appears that all other event code is properly zeroing the structure,
it's these two places.
