With the deprecation of `BT_LE_ADV_OPT_USE_NAME` and
`BT_LE_ADV_OPT_FORCE_NAME_IN_AD` samples were updated to not use the
macro adding the device name in the advertising/scan response data
anymore.
Instead the name was explicitly added to the scan response data in
`periodic_adv` sample. But because it was using an extended advertiser
and was already adding data in the AD, the name should have been put in
the advertising data and not the scan response data.
Update the sample to add the device name in the advertising data.
