Fix crashing of VisualScript due to...

Attempting to move the function node to another function whose data connection is a dependency of the node the specific node being moved to a different function during changes to sequence connections.
By skipping, if the from_node is a function_node during the data connection dependencies scan.
Should fix #37991
