[LU-4642] unify lu_object_{find,locate} interfaces to return "-ENOENT" for NULL case

Wed, 5 Nov 2014 00:20:48 +0000

Currently, lu_object_locate() will return NULL for the case of not found the required object (slice), but related lu_object_find_xxx() may return "-ENOENT" for that. Such inconsistent behaviour will confuse the callers. We prefer to make them all to return "-ENOENT" for the case of not found the object.
