In commit 232d2d60aa5469bb097f55728f65146bd49c1d25

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.
