ceph: make lease code DN specific
The lease code includes a mask in the CEPH_LOCK_* namespace, but that
namespace is changing, and only one mask (formerly _DN == 1) is used, so
hard code for that value for now.
If we ever extend this code to handle leases over different data types we
can extend it accordingly.
