of: reserved-memory: ignore disabled memory-region nodes
Ignore disabled nodes in the memory-region nodes list and continue to initialize the rest of enabled nodes. Check if the "reserved-memory" node is available and if it's not available, return 0 to ignore the "reserved-memory" node and continue parsing with next node in memory-region nodes list.
