Subject: [PATCH] NVMe: Add Quirk Delay before CHK RDY for Seagate Nytro Flash
 Storage
Git-commit: 0302ae60fc2368de5c561be49e2d9ea26dd462de
Patch-mainline: v4.18-rc1
References: bsc#1104967,FATE#325924

Add Seagate Nytro Flash Storage nvme drive to quirk list for
NVME_QUIRK_DELAY_BEFORE_CHK_RDY, which solves a bug where the drive is
probed on hot-add before the firmare is ready, I/O errors are generated
while reading sector 0, and linux is "unable to read partition table".
