AchievementManager: Fix unknown hash achievements deadlock

Browse source 
Within AchievementManager, CloseGame being called when LoadGame fails was causing m_queue.Cancel to be called within a lock when Cancel itself locks until it is empty, causing a deadlock. This is resolved by cancelling the queues outside of the lock when they are safe to wait for resolutions.
