Concatenating strings is not a very efficient approach. And in this case fully unnecessary. We also need some rules to make use of those hwdb entries. PCI needs to be 8 characters, not 4. And we need to use uppercase hexadecimal for both. With udev rules this made no difference, but hwdb match is case sensitive. Fixes #16119.
