fixup: sparse halo range policy

[streeve]

Breaking with Kokkos develop:

no known conversion for argument 1 from 
'Kokkos::RangePolicy<Kokkos::OpenMP>::member_type' {aka 'long unsigned int'} to 
'const Kokkos::Impl::AtomicDataElement<Kokkos::ViewTraits<int [2], Kokkos::HostSpace, Kokkos::MemoryTraits<4> > >&'```

<kokkos>/include/Kokkos_ExecPolicy.hpp:272:14: error: no matching conversion for static_cast from 'member_type' (aka 'unsigned long') to 'Kokkos::Impl::AtomicDataElement<Kokkos::ViewTraits<int[2], Kokkos::HostSpace, Kokkos::MemoryTraits<4>>>'
    warn |= (static_cast<IndexType>(static_cast<member_type>(bound)) != bound);
             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

@ldh4 this is interesting.

In the constraint we ensure convertibility from the user-provided argument to the policy index type but in the precondition check we do a roundtrip conversion and here it turns out the reverse conversion is not possible.
