langmuir cell parameterization and sea ice

Description

Langmuir cell parameterization should not be used below sea ice. In the current version of the code, the parameterization is applied even when sea ice is present.

Attached to this ticket is a corrected version of zdftke.F90 in which the production term of TKE by the langmuir cells is multiplied by the fraction of ice free water (1-fr_i(ji,jj,jk)). This is similar to what is done in the wave breaking scheme (controlled by the glag nn_etau). I made a test with this correction and it seems to work as it should.
