Memory leak in dep_engine.c

When we load the dep_engine, we fetch the out-fault phases and assign them to the configuration. During the fetching process a new array list is created. This contains the phases. However, before assigning it, we have duplicated the array list and assigned the duplicate. And, during the process we have not freed the initial (fetched) array list.

While going through the code, I understood that a duplicate is not necessary as the fetching process already creates a duplicate. Thus, I have removed the duplicate (new_out_fault_phases) and assigned the array list that was fetched (out_fault_phases), to the configuration.

This resolves the memory leak. (refer diff.txt)
