mm: write_cache_pages terminate quickly
commit d5482cdf8a0aacb1e6468a97d5544f5829c8d8c4 upstream.
Terminate the write_cache_pages loop upon encountering the first page past
end, without locking the page. Pages cannot have their index change when
we have a reference on them (truncate, eg truncate_inode_pages_range
performs the same check without the page lock).
