For pNFS direct writes, layout driver may dynamically allocate ds_cinfo.buckets. So we need to take care to free them when freeing dreq. Ideally this needs to be done inside layout driver where ds_cinfo.buckets are allocated. But buckets are attached to dreq and reused across LD IO iterations. So I feel it's OK to free them in the generic layer.
