This reverts commit 876c75fe87.
The patch seems to cause usb devices to get some attributes set from the parent
PCI device. 'hwdb' builtin has support for breaking iteration upwards on usb
devices. But when '--subsystem=foo' is specified, iteration is continued. I'm
sure it *could* be figured out, but it seems hard to get all the combinations
correct. So let's revert to functional status quo ante, even if does the lookup
more than once unnecessarily.
Fixes #18125.
