#1581513 — [PATCH 6/6] [media] go7007: improve subscribe event handling

From: Gustavo Padovan <gustavo.padovan@collabora.com>

We already check for the V4L2_EVENT_CTRL inside
v4l2_ctrl_subscribe_event() so just move this function to the default:
branch of the switch and let it does the job for us.
