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.

I would trim this down.
