Windows: AFSCleanup Flush Data decision

AFSCleanup() should instruct the cache manager to flush dirty
data when the Context Control Block indicates that the handle
being closed was opened for writing and was granted appropriate
permissions.   The decision to flush should not be dependent on
the open handle count because the last handle might belong to
an authentication group that does not have write permission.
