[PATCH] nvme-cli: smart-log: Allow negative values for temp sensors.

[Chaitanya Kulkarni]

HGST devices allowed to produce valid negative values for
"Temperature Sensor 1" of the smart-log command. Change the
temperature sensor value from unsigned to signed so that
negative values will be printed correctly.
