platform/x86: msi-laptop: Fix old-ec check for backlight registering

Commit 2cc6c717799f ("msi-laptop: Port to new backlight interface
selection API") replaced this check:

	if (!quirks->old_ec_model || acpi_video_backlight_support())
		pr_info("Brightness ignored, ...");
	else
		do_register();

With:

	if (quirks->old_ec_model ||
	    acpi_video_get_backlight_type() == acpi_backlight_vendor)
		do_register();

But since the do_register() part was part of the else branch, the entire
condition should be inverted.  So not only the 2 statements on either
side of the || should be inverted, but the || itself should be replaced
with a &&.

In practice this has likely not been an issue because the new-ec models
(old_ec_model==false) likely all support ACPI video backlight control,
making acpi_video_get_backlight_type() return acpi_backlight_video
turning the second part of the || also false when old_ec_model == false.
