ACPI: PCI: Fix device reference counting in acpi_get_pci_dev()
Commit 63f534b8bad9 ("ACPI: PCI: Rework acpi_get_pci_dev()") failed
to reference count the device returned by acpi_get_pci_dev() as
expected by its callers which in some cases may cause device objects
to be dropped prematurely.
Add the missing get_device() to acpi_get_pci_dev().
Fixes: 63f534b8bad9 ("ACPI: PCI: Rework acpi_get_pci_dev()")
