PCI/ACPI: Fix pci_acpi_preserve_config() memory leak

Browse source

[ Upstream commit fac679df75 ]

pci_acpi_preserve_config() leaks memory by returning early without freeing
the ACPI object on success. Fix that by always freeing the obj, which is
not needed by the caller.

Fixes: 9d7d5db8e7 ("PCI: Move PRESERVE_BOOT_CONFIG _DSM evaluation to pci_register_host_bridge()")
