Incorrect halo update for calving flux

[aekiss]

There's a bug here:

cice5/drivers/auscom/cpl_interface.F90

Line 710 in edcfa6f

call ice_HaloUpdate(calv0, halo_info, field_loc_center, field_type_vector)

Calving flux is a scalar, so this should be

  call ice_HaloUpdate(calv0, halo_info, field_loc_center, field_type_scalar)

This hasn't affected any production runs to date, because we add the solid runoff into the liquid runoff and don't use the solid runoff: COSIMA/access-om2#155 (comment)

It also doesn't explain the tripole seam bug COSIMA/access-om2#86 as this halo bug was introduced years later in commit 3bbef26
