This patch removes some questionable code that attempted to make a
no-longer-used page easier to reclaim.
Calling metapage_writepage against such a page will not result in any
I/O being performed, so removing this code shouldn't be a big deal.
[ It's likely that we could have just replaced the "clear_page_dirty()"
call with a call to "cancel_dirty_page()" instead, but in the
meantime this is cleaner and simpler anyway, so unless there is some
overriding reason (and Dave implies there isn't) I'll just use this
patch as-is. - Linus ]
