Subject: PCI: xgene: Remove leftover pci_scan_child_bus() call

Git-commit: 94b9d290b753cbbc87971ee134511245f5872a83
Patch-mainline: v4.16-rc1
References: fate#326572

The changes in commit 9af275be15f7 ("PCI: xgene: Convert PCI scan API to
pci_scan_root_bus_bridge()") converted the xgene PCI host driver to
the new pci_scan_root_bus_bridge() bus scanning API but erroneously left
the existing pci_scan_child_bus() call in place which resulted in duplicate
PCI bus enumerations.

Remove the leftover pci_scan_child_bus() call to properly complete the API
conversion.

Fixes: 9af275be15f7 ("PCI: xgene: Convert PCI scan API to pci_scan_root_bus_bridge()")
