Subject: [PATCH] nvme-pci: add quirk for Wodposit WPBSNM8-256GTP to disable secondary temp thresholds

Secondary temperature thresholds (temp2_{min,max}) were not reported
properly on this NVMe SSD. This resulted in an error while attempting to
read these values with sensors(1):

  ERROR: Can't get value of subfeature temp2_min: I/O error
  ERROR: Can't get value of subfeature temp2_max: I/O error

Add the device to the nvme_id_table with the
NVME_QUIRK_NO_SECONDARY_TEMP_THRESH flag to suppress access to all non-
composite temperature thresholds.
