PCI: Rename CRS Completion Status to RRS
PCIe r6.0 changed the abbreviation for "Configuration Request Retry Status"
Completion Status from "CRS" to "RRS" and uses the terminology of
"Configuration RRS Software Visibility" instead of "CRS Software
Visibility".
Align the Linux usage with the r6.0 spec language. No functional change
intended.
It's confusing to make this change, but I think "RRS" *is* a better
abbreviation because it was easy to interpret "CRS" as "Completion Retry
Status", which really didn't make any sense.
