PCIe: fix 'symbol not declared' sparse warnings

While refreshing my physical PCI slot series against upstream, I
noticed a few simple sparse/compile warnings that were easy to
fix.

Fix the following sparse warnings in PCIe:

	drivers/pci/pcie/aer/aerdrv.c:86:6: warning: symbol 'pci_no_aer'
	was not declared. Should it be static?
	drivers/pci/pcie/portdrv_bus.c:21:17: warning: symbol
	'pcie_port_bus_type' was not declared. Should it be static?
