From: angquan yu <angquan21@gmail.com>

This commit fixes a compiler warning in the file
x86_64/nx_huge_pages_test.c, which was caused by improper
macro expansion of '__TEST_REQUIRE'.

Warning addressed:
- The warning was triggered by the expansion of the '__TEST_REQUIRE'
macro, indicating a potential issue in how the macro was being
used or expanded.

Changes made:
- Modified the usage of the '__TEST_REQUIRE' macro to ensure proper
expansion. This involved explicitly passing the expected magic token
(MAGIC_TOKEN) and a descriptive error message to the macro.
- The fix enhances clarity in the macro usage and ensures that
the compiler correctly interprets the intended logic, thereby
resolving the warning.
