Morph 72b22fd433 service: filesystem: Return proper error codes for CreateFile 
This improves the accuracy of CreateFile by returning the correct error codes on certain conditions (parent directory does not exist, path already exists).

This fixes saving and the loading of existing saves in New Pokemon Snap
