Miaoqian Lin 96cf850093 slimbus: ngd: Fix reference count leak in qcom_slim_ngd_notify_slaves 
The function qcom_slim_ngd_notify_slaves() calls of_slim_get_device() which
internally uses device_find_child() to obtain a device reference.
According to the device_find_child() documentation,
the caller must drop the reference with put_device() after use.

Found via static analysis and this is similar to commit 4e65bda827
("ASoC: wcd934x: fix error handling in wcd934x_codec_parse_data()")
