interconnect: qcom: sdm845: Walk the list safely on node removal

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

In addition to the above, instead of duplicating the code, call qnoc_remove()
directly from the probe function error path.
