[Impact]
A user reported his NVMe went out to lunch after S3.

[Fix]
Disable APST for this particular NVMe + Motherboard setup.

[Test]
User confirmed this quirk works for his system.

[Regression Potential]
Very Low. This applies to a specific device setup, also user can
override this quirk by "nvme_core.force_apst=1".

Please try to remember to include patches like this for the development
release as well. I have applied it to bionic/master-next. Thanks!
