Subject: [PATCH v1 2/3] iio: core: Clean up device correctly on iio_device_alloc() failure

Once we called device_initialize() we have to call put_device()
on it. Refactor the code to make it in the right order.

Fixes: fe6f45f6ba22 ("iio: core: check return value when calling dev_set_name()")
Fixes: 847ec80bbaa7 ("Staging: IIO: core support for device registration and management")
