Anton Blanchard 0c75ba2254 e1000e: Fix oops caused by ASPM patch. 
Commit 6f461f6c7c
("e1000e: enable/disable ASPM L0s and L1 and ERT according to hardware errata")
oopses on one of my ppc64 boxes with a NULL pointer (0x4a):

Unable to handle kernel paging request for data at address 0x0000004a
Faulting instruction address: 0xc0000000004d2f1c
cpu 0xe: Vector: 300 (Data Access) at [c000000bec1833a0]

Seems like pdev->bus->self == NULL. I haven't touched pci in a long time
so I'm trying to remember what this means (no pcie bridge perhaps?)

The patch below fixes the oops for me.
