ACPI: video: Release PCI device reference after lookup

Browse Source 
video_detect_portege_r100() uses pci_get_device() only as a boolean
check for the Trident CyberBlade XP4m32 device. pci_get_device() takes a
reference on a matching PCI device, but the callback returns without
releasing it.

Drop the reference after selecting the vendor backlight quirk so the PCI
device can be released normally.
