/**
* list_count_nodes - count the number of nodes in a list
* @head: the head of the list
*
* This function iterates over the list starting from @head and counts
* the number of nodes in the list. It does not modify the list.
*
* Context: Any context. The function is safe to call in any context,
* including interrupt context, as it does not sleep or allocate
* memory.
*
* Return: the number of nodes in the list (excluding the head)
