HID: sensor-hub: fix potential memory leak
hsdev is not freed in sensor_hub_probe when kasprintf inside the for loop fails. This is because hsdev is not set to platform_data yet (to be freed by the code in the err_no_mem label). So free the memory explicitly in the 'if' branch, as this is the only place where this is (and will) be needed.
