[PATCH v2 1/2] PCI: rcar: Fix error exit path

[Harunobu Kurokawa]

From: Lorenzo Pieralisi <lorenzo.pieralisi@xxxxxxx>

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.

Fixes: 90634e854079 ("PCI: rcar: Convert PCI scan API to pci_scan_root_bus_bridge()")
