    libafscp: Can't unlock something we've freed
    
    When we call _StatCleanup on a stored statent structure, it
    deletes the mutex, and frees the structure itself. This means it
    can't be called with a locked structure as the mutex deletion
    will fail, and then we'll try to reference freed memory when we
    later unlock that mutex.
    
    Fix this by unlocking the mutex before calling _StatCleanup. This
    is safe because the only reference to the structure visible to other
    threads must have been deleted by the time we reach this point.
