mm/filemap: remove unused parameter and change to void type for replace_page_cache_page()
Since commit 74d609585d8b ("page cache: Add and replace pages using the
XArray") was merged, the replace_page_cache_page() can not fail and always
return 0, we can remove the redundant return value and void it. Moreover
remove the unused gfp_mask.
