mm/swap.c: clear PageActive before adding pages onto unevictable list
As a result of commit 13f7f78981e4 ("mm: pagevec: defer deciding which
LRU to add a page to until pagevec drain time"), pages on unevictable
lists can have both of PageActive and PageUnevictable set. This is not
only confusing, but also corrupts page migration and
shrink_[in]active_list.
This patch fixes the problem by adding ClearPageActive before adding
pages into unevictable list. It also cleans up VM_BUG_ONs.
