Sensor hw_id is int type other u32, is_sensor_enabled
should use int to compare, this fix smatch warning:
drivers/thermal/qcom/tsens-common.c:72
is_sensor_enabled() warn: unsigned 'hw_id' is never less than zero.
Fixes: 3e6a8fb33084 ("drivers: thermal: tsens: Add new operation to check if a sensor is enabled")
