ACPI: PCI: pci_link: clear driver_data before free
acpi_pci_link_remove() frees the link object without clearing the ACPI
device's driver_data pointer. The ACPI device survives hot-removal and
can later be retrieved by acpi_fetch_acpi_dev(), leaving callers with a
dangling pointer.
Clear driver_data before freeing the link.
Fixes: db89b4f0dbab ("ACPI: catch calls of acpi_driver_data on pointer of wrong type")
