platform/x86: acer-wmi: Ignore backlight event
[ Upstream commit 444a9256f8d106e08a6bc2dc8ef28a8699e4b3ba ]
On the Acer Nitro AN515-58, the event 4 - 0 is send by the ACPI
firmware when the backlight up/down keys are pressed. Ignore this
event to avoid spamming the kernel log with error messages, as the
acpi-video driver already handles brightness up/down events.
