Tpetra: proposed changes to handle processes with zero rows

I am currently working on a project at Sandia about multigrid preconditioners where some tasks have no matrix rows. This has revealed two places where KokkosKernels and Tpetra throw an exception.
I would like to propose a change of the conditions to throw the exception, checking also that the number of rows be different from zero.
