    Windows: after dir enum adjust dir scache LRU
    
    During a directory enumeration the directory scache object
    is reference counted so it can't be recycled.  However, if
    there are more directory entries than the maximum number
    of cached scache objects the directory scache object will
    end up being the next object to be recycled after the refcount
    is dropped.  Since the directory is clearly a hot object, before
    dropping the reference, adjust the scache LRU position so that
    it is the last object to be recycled.
    
    Fix the variable name for the directory scache to be 'dscp'
    for consistency.
