PCI: rcar-host: Remove unused LIST_HEAD(res)

Remove the unused LIST_HEAD(res) declaration from rcar_pcie_hw_enable().

The macro instantiation defines an unused 'struct list_head res' variable,
which conflicts with a valid resource loop-local 'struct resource *res'
declaration further down in the function, triggering a compiler variable
shadowing warning:

 drivers/pci/controller/pcie-rcar-host.c:357:34: warning: declaration of 'res' shadows a previous local [-Wshadow]
 357 |                  struct resource *res = win->res;
