Description

When removing an ACL, the logic must restore the group permission previously stored in an ACL entry back into the group permission bits. The logic for this in AclTransformation#removeINodeAcl assumes that the group entry must be found in the former ACL. This is not the case when removing the ACL from an inode that only had a default ACL and not an access ACL.
