Subject: pci/pcie/aer/aerdrv_acpi.c: inconsequent NULL checking

The Coverity checker spotted the following inconsequent NULL checking 
introduced by commit 3c75e23784e6ed5f4841de43d0750fd9b37bafcb:

<--  snip  -->

...
int aer_osc_setup(struct pcie_device *pciedev)
{
...            vvvvvvvvv
        while (pdev->bus && pdev->bus->self)
                pdev = pdev->bus->self;
        handle = acpi_get_pci_rootbridge_handle(
                pci_domain_nr(pdev->bus), pdev->bus->number);
...                                       ^^^^^^^^^^^^^^^^^

<--  snip  -->
