[PATCH v3 3/4] soc: qcom: smem_state: fix missing of_node_put in error path

[Krzysztof Kozlowski]

If of_parse_phandle_with_args() succeeds, the OF node reference should
be dropped, regardless of number of phandle arguments.

Changes in v3:
1. Add Rb tag, combine from other series.
I don't quite get why rest of other series was applied, but not this fix.
