filemap: remove use of wait bookmarks

Browse source 
The original problem of the overly long list of waiters on a locked page
was solved properly by commit 9a1ea439b1 ("mm:
put_and_wait_on_page_locked() while page is migrated").  In the meantime,
using bookmarks for the writeback bit can cause livelocks, so we need to
stop using them.
