ceph: set mds_wanted when MDS reply changes a cap to auth cap
When adjusting caps client wants, MDS does not record caps that are not allowed. For non-auth MDS, it does not record WR caps. So when a MDS reply changes a non-auth cap to auth cap, client needs to set cap's mds_wanted according to the reply. Signed-off-by: Yan, Zheng <zheng.z.yan@intel.com>
