Subject: [PATCH] interconnect: qcom: icc-rpmh: Fix an error handling path in qcom_icc_rpmh_probe()

If of_platform_populate() fails, some resources need to be freed as already
done in the other error handling paths.

Fixes: 57eb14779dfd ("interconnect: qcom: icc-rpmh: Support child NoC device probe")
