libceph: calculate placement based on the internal data types
Instead of using the old ceph_object_layout struct, update our internal ceph_calc_object_layout method to use the ceph_pg type. This allows us to pass the full 32-bit precision of the pgid.seed to the callers. It also allows some callers to avoid reaching into the request structures for the struct ceph_object_layout fields.
