Create pci slot files for SMBIOS Type 9 entries

Commit Message

[e-mail] Feb. 10, 2016, 2:50 p.m. UTC

The following diff builds on the "[PATCHv3] Save SMBIOS Type 9 System Slots"

This will create a /sys/bus/pci/slots/XXX file for each Type 9 entry.  This will be used for systemd enumeration of NICs.
