New test binaries must be ignored by a .gitignore in their own directory.
Move this entry to testcases/kernel/mem/hugetlb/hugemmap/.gitignore as
/hugemmap33.

Use TST_EXP_PASS_PTR_VOID() for expected successes and
TST_EXP_FAIL_PTR_VOID(..., ENOMEM) for expected failures instead of manually
combining TESTPTR(), errno checks, and tst_res(). Keep only the cleanup logic
that depends on TST_PASS or TST_RET_PTR.

Verdict - Needs revision
