PCI: rcar: Handle rcar_pcie_parse_request_of_pci_ranges() failures
[ 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.
Fixes: 5d2917d469faab72 ("PCI: rcar: Convert to DT resource parsing API")
