Subject: Revert "udev: do not execute hwdb builtin import twice or thrice"
This reverts commit 876c75fe870846b09b54423a6b719d80bc879b27.
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.
(cherry picked from commit 451ba55fecd8b494add2001b3ca3c1915c8fd655)
