dcache: Translating dentry into pathname without taking rename_lock

The __dentry_path locking was changed and the variable error was intended to be moved outside of the loop. Unfortunately the inner declaration of error was not removed. Resulting in a version of __dentry_path that will never return an error.

Remove the problematic inner declaration of error and allow __dentry_path to return errors once again.
