Fix type mismatch warnings:
  hugetlb-madvise.c:30:25: warning: comparison of integer expressions of different signedness: ‘int’ and ‘long unsigned int’ [-Wsign-compare]
     30 |                 if (fhp != (exp_free)) {                                \
        |                         ^~
  hugetlb-madvise.c:114:9: note: in expansion of macro ‘validate_free_pages’
    114 |         validate_free_pages(free_hugepages - NR_HUGE_PAGES);
        |         ^~~~~~~~~~~~~~~~~~~
