media: uvcvideo: Prevent heap overflow when accessing mapped controls
commit 7e09f7d5c790278ab98e5f2c22307ebe8ad6e8ba upstream.
The size of uvc_control_mapping is user controlled leading to a
potential heap overflow in the uvc driver. This adds a check to verify
the user provided size fits within the bounds of the defined buffer
size.
