Thomas Zimmermann 105a940416 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.

v2:
	* update comment and fix spelling (Sam)
