Add VNF callback for ERROR.indication

Created a function nr_error_ind_cb for the VNF that takes a received ERROR.indication and shows some details regarding the reported error from the PNF, since up until now it was not handled and treated as an unknown message.
Proper error handling procedure not created, only shows that the error occurred.
