iio: hid-sensor-attributes: Fix sensor property setting failure. When system bootup without get sensor property, set sensor property will be fail. If no get_feature operation done before set_feature, the sensor properties will all be the initialized value, which is not the same with sensor real properties. When set sensor property it will write back to sensor the changed perperty data combines with other sensor properties data, it is not right and may be dangerous. In order to get all sensor properties, choose to read one of the sensor properties(no matter read any sensor peroperty, driver will get all the peroperties and return the requested one).
