An IBM OpenPower partner reports their system with a bunch of NVMe

[Fix]

Pick patch db2173198b9513f7add8009f225afa1f1c79bcc6 upstream.

[Testing]

IBM reports that this patch fixes the user's issue.

[Regression Potential]

The patch is already in Cosmic
(db33bbe77b9594133fecf0dc290322437170627f) and in some stable trees
(1eb08e7b192d2c412175f607cf51449c916abd57 in 4.14.y).  It only affects
