/**
Safe destroy nodes in a linked list, and return the length of the list after all possible operations finished.
Destroy network child instance list by list traversals is not safe due to graph dependencies between nodes.
This function performs a safe traversal to destroy these nodes by checking to see if the node being destroyed
has been removed from the list or not.
If it has been removed, then restart the traversal from the head.
If it hasn't been removed, then continue with the next node directly.
This function will end the iterate and return the CallBack's last return value if error happens,
or retrun EFI_SUCCESS if 2 complete passes are made with no changes in the number of children in the list.
@param[in] List The head of the list.
@param[in] CallBack Pointer to the callback function to destroy one node in the list.
@param[in] Context Pointer to the callback function's context: corresponds to the
parameter Context in NET_DESTROY_LINK_LIST_CALLBACK.
@param[out] ListLength The length of the link list if the function returns successfully.
@retval EFI_SUCCESS Two complete passes are made with no changes in the number of children.
@retval EFI_INVALID_PARAMETER The input parameter is invalid.
@retval Others Return the CallBack's last return value.
