    Description

      In the restore case of hsm_cdt_request_completed(), if the copytool returned success but the layout swap fails then we get an unreadable file with HS_RELEASED clear but LOV_PATTERN_F_RELEASED set.

      Perhaps the new HSM attributes should be applied to the volatile object before layout swap, and hsm_swap_layouts() should call mo_swap_layouts() with SWAP_LAYOUTS_MDS_HSM set.
