[PATCH] hugetlb_cgroup: remove unused variable 'i'

[Ralph Campbell]

Compiling tests in tools/testing/selftests/vm/ results in a C compiler
warning:

write_to_hugetlbfs.c: In function âmainâ:
write_to_hugetlbfs.c:77:16: warning: unused variable âiâ
   77 |  unsigned long i;

Delete the unused variable.
