LU-13437 mdc: remote object support getattr from cache

LU-13437 mdc: remote object support getattr from cache

For historical reason, IT_GETATTR lock revalidate matches
LOOKUP|UPDATE|PERM lock bits because for MDS < 2.4, permission is
protected by LOOKUP lock, but this will cause remote object not
able to match the cached lock because LOOKUP and UPDATE lock are
fetched separately.

Add sanity 803b, and rename 803 to 803a.
