[PATCH 04/10] PCI/AER: Log messages with pci_dev, not pcie_device

[Bjorn Helgaas]

From: Frederick Lawler <fred@xxxxxxxxxxxx>

Log messages with pci_dev, not pcie_device.  Factor out common message
prefixes with dev_fmt().

Example output change:

  - aer 0000:00:00.0:pci002: AER enabled with IRQ ...
  + pcieport 0000:00:00.0: AER: enabled with IRQ ...
