ubifs: Fix unlink code wrt. double hash lookups
When removing an encrypted file with a long name and without having the key we have to be able to locate and remove the directory entry via a double hash. This corner case was simply forgotten. Fixes: 528e3d178f25 ("ubifs: Add full hash lookup support") Reported-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at> Signed-off-by: Richard Weinberger <richard@nod.at>
