While refactoring code the return statement became corrupted, fix it by
returning the correct return code.

Fixes: 897e371389e77514 ("media: rcar-vin: simplify how formats are set and reset"

* Changes since v2
- Set ret to 0 if the subdevice do not implement set_fmt and returns
  -ENOIOCTLCMD instead of returning the not implemented error.
