[PATCH] Revert "nvme-pci: add quirks for Samsung X5 SSDs"

[Jason A. Donenfeld]

This reverts commit bc360b0b1611566e1bd47384daf49af6a1c51837.

This matches the hardware identifier of the Samsung 970 EVO Plus, a very
popular internal laptop NVMe drive, which is not the Samsung X5, an
external thunderbolt drive. In particular, this causes:

1) a 2.3 second boot time delay; and
2) disabling of deep power saving states.

So just revert this until whatever funny business can be worked out
regarding Samsung's PCI IDs.
