backlight: fix detection of multiple graphic cards
Follow-up for e0504dd011189d97a1ea813aabfe1e696742bcf5.
Hopefully, devices in PCI subsystem have some properties, thus have
their udev database file. But, that may not be true. Here, we only read
sysattrs of enumerated devices, hence it is not necessary to check if
the device is initialized or not.
