platform/chrome: fix double-free in chromeos_laptop_prepare()
If chromeos_laptop_prepare_i2c_peripherals() fails after allocating memory
for 'cros_laptop->i2c_peripherals', this memory is freed at 'err_out' label
and nonzero value is returned. Then chromeos_laptop_destroy() is called,
resulting in double-free error.
