sargo/bonito: mouse cursor of Linux doesn't show on screen

[utzcoz]

The view can response mouse hover, but cursor doesn't show on Linux. I tested it with Android's simulated secondary display. I also found some exception logs:

Looks like mflinger doesn't lock buffer correctly.

After enabling debug of mflinger, and updating system, this exception disappeared, but cursor surface didn't show on screen.

Looks like cursor layer is not visible.
