memblock_free_pages() currently takes both a struct page * and the corresponding PFN. The page pointer is always derived from the PFN at call sites (pfn_to_page(pfn)), making the parameter redundant and also allowing accidental mismatches between the two arguments. Simplify the interface by removing the struct page * argument and deriving the page locally from the PFN, after the deferred struct page initialization check. This keeps the behavior unchanged while making the helper harder to misuse.
