[PATCH v2 2/4] iio: light: cm36651: Make use of the helper function dev_err_probe()

[Cai Huoqing <caihuoqing@baidu.com>]

When possible use dev_err_probe help to properly deal with the
PROBE_DEFER error, the benefit is that DEFER issue will be logged
in the devices_deferred debugfs file.
Using dev_err_probe() can reduce code size, and the error value
gets printed.
