rbd: store and use obj_request->object_no

Browse source

object_no can be trivially formatted into an object name.  We already
store object names in OSD requests with special care to avoid dynamic
allocations for short names.  Storing a name in obj_request, obtained
as below (!), is a waste and will be removed in the next commit.

    name = kmem_cache_alloc(rbd_segment_name_cache, ...);
    snprintf(name, ...);
    obj_request->object_name = kstrdup(name);
    kmem_cache_free(rbd_segment_name_cache, name);
    ...
    ceph_oid_aprintf(..., "%s", obj_request->object_name);
