mm: remove unused arg of set_page_dirty_balance()

commit ed6d7c8e578331cad594ee70d60e2e146b5dce7b upstream.

There's only one caller of set_page_dirty_balance() and that will call it
with page_mkwrite == 0.

The page_mkwrite argument was unused since commit b827e496c893 "mm: close
page_mkwrite races".
