Tpetra: CrsGraph: Kokkos refactor: removed unused typedef.

The typedef is only unused in a release build.  Some compilers emit
warnings for declared but unused typedefs, so it's best to fix it.
Tpetra: CrsMatrix (Kokkos refactor): improved descri{be,ption}
Tpetra: CrsMatrix: Added more output to Transpose unit test.

For some reason, with Kokkos Refactor Nodes, this test (in
CrsMatrix_UnitTests3) fails in SERIAL_RELEASE but not in MPI_DEBUG.
The (one-)norms are totally wrong.  So, I added a bit more output to
the test.  It helps a little bit with interpreting the results.

MueLu: disabling CoordinateMap test temporarily.

This test is hanging.  I'm disabling it until I have time to look into
why.  See bugzilla report for more info.
