Anton V. Shokurov 1ab8c3fc75 [media] uvcvideo: Fix reading the current exposure value of UVC ...

V4L2_CID_EXPOSURE_ABSOLUTE property does not return an updated value when
autoexposure (V4L2_CID_EXPOSURE_AUTO) is turned on. This patch fixes this
issue by adding the UVC_CTRL_FLAG_AUTO_UPDATE flag.

Tested on a C920 camera.
