kernel: Booter-Unload success + SM order table (unload/reload cycle works)

- gsp_emu_poll_boot generic SEC2 kick path: clear SEC2_MAILBOX0=0
  (success) - Booter Unload during GPU shutdown read a stale 0xff,
  failing the unload and killing the subsequent re-init ('Booter failed
  with non-zero error code: 0xff' -> RmInitAdapter 0x40). A SEC2 kick
  after a completed boot is a GSP shutdown/reload: clear boot state.
  Driver unload/reload cycle (last close -> RmShutdown, next open ->
  RmInitAdapter) now works.
- STATIC_KGR_GET_GLOBAL_SM_ORDER(0x20800a22): TU104 topology 6 GPC x
  4 TPC x 2 SM = 48 SMs/24 TPCs on GR0. kgrStaticInit is init-critical
  (NV_CHECK_OK_OR_GOTO); zeros left numSm=0 and NVML spun on empty
  topology.
