[petsc-dev] Compilation errors with kokkos and --with-scalar-type complex

[Stefano Zampini]

Incidentally, I found PETSc does not compile when configured using

--with-scalar-type=complex --with-kokkos-dir=....
--with-kokkos_kernels-dir=...

Some fixes are trivial, others require some more thought.

Thanks
