 Write a function `ListRemoveIf` that removes all elements that are equal to the `data_ref` introduced in the argument of the function.
 
-- In case the list is empty print the message `no data on list`.
-
-- Use pointers wen ever you can.

 ### Expected function and structure
 
 ```go
-type node struct {
+type NodeL struct {
 	data interface{}
-	next *node
+	next *NodeL

-type list struct {
-	head *node
