nvme-pci: add quirk for missing secondary temperature thresholds
On Kingston KC3000 and Kingston FURY Renegade (both have the same PCI
IDs) accessing temp3_{min,max} fails with an invalid field error (note
that there is no problem setting the thresholds for temp1).
This contradicts the NVM Express Base Specification 2.0b, page 292:
The over temperature threshold and under temperature threshold
features shall be implemented for all implemented temperature sensors
(i.e., all Temperature Sensor fields that report a non-zero value).
Define NVME_QUIRK_NO_SECONDARY_TEMP_THRESH that disables the thresholds
for all but the composite temperature and set it for this device.
