mds: properly update capability's client_follow

If snap inode exists, capability's client_follow has already been
updated by MDCache::cow_inode(). So we only update client_follow
when the inode was not COWed.

Besides, we need to check return of SnapRealm::get_snap_following().
It can return CEPH_NOSNAP, which is clearly invalid for client_follows.
