Fix #1631

Revert one line from #1620 which changed CrsMatrix::values_type (a 1D
view) to be default_layout instead of LayoutRight. This seemed totally
reasonable (the graph's rowptrs/entries already used default_layout),
but the change makes spmv give wrong answers with Sacado PCE or MPVector
as the scalar type.
