[media] drivers/media/usb/usbvision/usbvision-core.c: Remove useless return variables

This patch remove variables that are initialized with a constant,
are never updated, and are only used as parameter of return.
Return the constant instead of using a variable.

Verified by compilation only.

... when != ret
    when strict
return
- ret
+ C
;
// </smpl>
