Incorrect halo depths in some adjoint kernels

[mo-alistairp]

For some adjoint kernels the halo depth is not being set correctly. This has led to PSyKAl-lite code -

• invoke_atl_poly_adv_update_kernel_type
• 'invoke_atl_w3h_adv_upd_kernel_type'

in science/adjoint/source/psy/transport/mol/invoke_atl_poly_adv_update_mod.f90 and science/adjoint/source/psy/transport/mol/invoke_atl_w3h_adv_upd_mod.f90 respectively.

This is documented in PSyclone issue #2886
