[PATCH v2 2/5] interconnect: qcom: qcs404: Walk the list safely on node removal

[Georgi Djakov <georgi.djakov@linaro.org>]

As we will remove items off the list using list_del(), we need to use the
safe version of list_for_each_entry().

Fixes: 5e4e6c4d3ae0 ("interconnect: qcom: Add QCS404 interconnect provider driver")
