window/x11: Keep buffer size if resize is not allowed

Browse source 
Mutter would deny the application the right to resize itself during an
interactive resize, to avoid the user and the client to fight for the
size.

When the client is not allowed to resize, it would use the client rect
rather than the buffer rect.

As a result, the client window with client side decorations would
quickly shrink to its minimum size.

Use the buffer rect instead, so that the size really remains the same.
