Merge branch 'irenavankova/ocn/fix-subglacial-config-attenuation' (PR #6672)

Fix variables in data subglacial runoff

This fixes a typo in PR #6508, where
  config_flux_attenuation_coefficient_runoff
was mistakenly used in kpp loop instead of
  config_flux_attenuation_coefficient_subglacial_runoff
These variables are only used for data subglacial runoff.

[BFB] for all tested configurations
