Fix race condition in release pages. There was a race condition where another thread could coalesce the free page run before we acquired the lock. In that case free_page_runs_.find will not find a run starting at fpr. Added a condition to handle this case. Also added handling for free page runs with begin with released pages but end with empty pages. Bug: 16191993 Change-Id: Ib12fdac8c246eae29c36f6a6728eb11d85553bbb
