ARM/PCI: Fix pcibios_init_resource() struct pci_host_bridge leak 

Since commit 97ad2bdcbe ("ARM/PCI: Convert PCI scan API to
pci_scan_root_bus_bridge()") the space for struct pci_sys_data is allocated
by pci_alloc_host_bridge() as part of the struct pci_host_bridge.

Therefore, failure paths must deallocate the entire pci_host_bridge by
using pci_free_host_bridge().

Fixes: 97ad2bdcbe ("ARM/PCI: Convert PCI scan API to pci_scan_root_bus_bridge()")
