[PATCH] PCI/AER: Forward declare struct pci_dev to avoid warning

[Tuomas Tynkkynen]

Forward declaring struct pci_dev in aer.h avoids this warning:

In file included from include/ras/ras_event.h:11:0,
                 from drivers/ras/ras.c:13:
include/linux/aer.h:38:44: warning: 'struct pci_devâ declared inside parameter list [enabled by default]
include/linux/aer.h:38:44: warning: its scope is only this definition or declaration, which is probably not what you want [enabled by default]
