current boot failure on NVME with and after 8e9fe9996a1f

On a Dell Latitude 5540 with two NVME disks, the last working commit 
from bisection is a9752e9ac8a6.

Anything beyond this fails on start up with ..

d5540 kernel: nvme1: Resetting controller due to a timeout.
d5540 kernel: nvme1: event="start"
d5540 kernel: nvme1: event="success"
d5540 kernel: nvme1: aborting outstanding i/o
d5540 kernel: nvme1: done aborting outstanding i/o

It seems that the PCI changes don't work for disks attached in this 
manner ..
