[PATCH 1/2] fbdev/defio: Early-out if page is already enlisted

Return early if a page is already in the list of dirty pages for deferred I/O. This can be detected if the page's list head is not empty. Keep the list head initialized while the page is not enlisted to make this work reliably. Signed-off-by: Thomas Zimmermann ---
