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. Signed-off-by: "Yan, Zheng" <zyan@redhat.com> Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
