Fix a double-free when daemon is restarting. #101

When pimd receives SIGHUP signal and in the Source-specific multicast case, it will restart and the sources list in the VIF table will be freed. However the source node gets double freed due to an error in walking the list. The correct pointer to the next node needs to be set.
