ceph: update wanted caps after resuming stale session
mds contains an optimization, it does not re-issue stale caps if
client does not want any cap.
A special case of the optimization is that client wants some caps,
but skipped updating 'wanted'. For this case, client needs to update
'wanted' when stale session get renewed.
