sna/video: Discard old video buffers when the frame size changes
Back in the good old days of the overlay, we only needed to care about
having a frame buffer large enough to hold the data. This changed with
the sprite interface which encodes the width x height into the
framebuffer and so we need to be careful when handing back a cached
buffer that it does indeed match the required dimensions.
