commit 80207910cd71b4e0e87140d165d82b5d3ff69e53

    kasan: move and hide kasan_save_enable/restore_multi_shot
    
     - Move kasan_save_enable/restore_multi_shot() declarations to
       mm/kasan/kasan.h, as there is no need for them to be visible outside
       of KASAN implementation.
    
     - Only define and export these functions when KASAN tests are enabled.
    
     - Move their definitions closer to other test-related code in report.c.
