[PATCH 17/24] PCI: Rename resource variable from r to res

[Ilpo Järvinen]

Resource is going to be passed in as argument aften an upcoming change.
Rename the struct resource variable from "r" to "res" to avoid using
one letter variable name in a function argument.

This rename is made separately to reduce churn in the upcoming change.
