[media] DaVinci-VPBE: Reduce the scope for a variable in vpbe_set_default_output()

Browse Source 
* Move the definition for the variable "ret" into an if branch
  so that an extra initialisation can be avoided at the beginning
  by this refactoring.

* Return a success code as a constant at the end.
