Subject: [PATCH v2] mm/page_alloc: Simplify free_page_is_bad by removing free_page_is_bad_report

From: Ye Liu <liuye@...inos.cn>

This patch refactors the free_page_is_bad function by directly calling
bad_page() instead of using the intermediary function
free_page_is_bad_report(). The removal of free_page_is_bad_report()
reduces unnecessary indirection, making the code cleaner and easier to
read.

The functionality remains the same, as free_page_is_bad_report() was
merely a wrapper for the bad_page() call. The patch also improves
maintainability by reducing the function call depth.
