maps007 test: fix for clang

Browse source 
CLang doesn't like explicit NULL pointer dereference:
> maps007.c:176:2: error: indirection of non-volatile null pointer will be deleted, not trap [-Werror,-Wnull-dereference]
>         *((int *) 0) = 0;
>         ^~~~~~~~~~~~
> maps007.c:176:2: note: consider using __builtin_trap() or qualifying pointer with 'volatile'
>

Apparently, we need to add volatile to make it happy.
