Subject: fix trilinos tpetra when using intel MKL

fix trilinos tpetra when using intel MKL

The choice to disable TPetra when using MKL lead to several downstream
Trilinos configuration errors. Instead, just disable the two
instantiations that are missing in MKL. Tested to work correctly with
Intel 19.0.5 and MKL.
