Fix the warnings by initializing and marking the variable as unused.
I've caught the warnings by using clang.

split_huge_page_test.c:303:6: warning: variable 'dummy' set but not used [-Wunused-but-set-variable]
  303 |         int dummy;
      |             ^
split_huge_page_test.c:343:3: warning: variable 'dummy' is uninitialized when used here [-Wuninitialized]
  343 |                 dummy += *(*addr + i);
      |                 ^~~~~
split_huge_page_test.c:303:11: note: initialize the variable 'dummy' to silence this warning
  303 |         int dummy;
      |                  ^
      |                   = 0
2 warnings generated.
