PCI: rcar: Fix error exit path
Commit 90634e854079 ("PCI: rcar: Convert PCI scan API to
pci_scan_root_bus_bridge()") converted PCI root bus scan API to the new
pci_scan_root_bus_bridge() API; in the process some error paths were not
updated correctly which may cause memory leaks.
Fix the driver error exit path reinstating the previous correct
error exit behaviour.
