Attachment: Check if device matches

Since our new fallback logic for D3D10 layers it's possible for a new device to be used after a driver reset. We're currently continuing to draw however we're trying to use cached bitmaps from the old device, this doesn't work. We should not use the cached bitmaps if they don't belong to the right device.

This patch simply tosses the cached bitmaps, this is not the best thing ever if actually using multiple devices simultaneously but we don't do that. To support that situation we should use a key-per-device for storing the user-data but I don't think it's worth adding that complexity to the code at this point. This is the simplest solution for now I believe.
