GpuManager's compatibleRenderDevice() returns nullptr for scanout devices that have no render device to pair with, such as evdi DisplayLink outputs. This caused deviceId() to be called on a null pointer whenever a buffer from another device is considered for direct scanout on such an output. On systems with a DisplayLink dock, this crashes kwin_wayland as soon as a fullscreen surface is shown on an evdi output. This change restores the previous behavior: If there is no compatible render device, treat the buffer as coming from another GPU and refuse direct scanout.
