[Spice-devel] [PATCH spice-gtk] spice-display: Check validity of cursor before unref

[Pavel Grunt]

Since 62f9144d6c5ac06cd76b76176644622c43c08541 the mouse cursor
is created when the widget is realized. The unref must be prevented.

The issue can happen when connecting using remote-viewer to
a multimonitor VM.
