Subject: PCI: rcar: Handle rcar_pcie_parse_request_of_pci_ranges() failures

From: Geert Uytterhoeven <geert+renesas@glider.be>


[ Upstream commit 83c75ddd816e979802bd244ad494139f28152921 ]

rcar_pcie_parse_request_of_pci_ranges() can fail and return an error
code, but this is not checked nor handled.

Fix this by adding the missing error handling.
