sched/addrenv: Miscellaneous clean-up and fixes

Browse Source 
- Remove the temporary "saved" variable when temporarily changing MMU
  mappings to access another process's memory. The fact that it has an
  address environment is enough to make the choice
- Restore nxflat_addrenv_restore-macro. It was accidentally lost when
  the address environment handling was re-factored.
