The modesetting driver still has an everlasting bug of invisible
cursor on cirrus and other KMS drivers where no hardware cursor is
supported. This patch is a part of an attempt to address it.
This patch particularly converts the current load_cursor_argb callback
of modesetting driver to load_cursor_argb_check so that it can return
whether the driver handles the hw cursor or falls back to the sw
cursor.
