page_counter: reduce struct page_counter size
The struct page_counter has explicit padding for better cache alignment.
The commit c6f53ed8f213a ("mm, memcg: cg2 memory{.swap,}.peak write
handlers") added a field to the struct page_counter and accidently
increased its size. Let's move the failcnt field which is v1-only field
to the same cacheline of usage to reduce the size of struct page_counter.
