Agrif update of ssh

Description
In NEMO3.2, ssha (after timestep) is computed in ssh_wzv at the beginning of the 'stp' routine and the transfer of the fields a->n and n->b is done in ssh_nxt, after dyn_nxt, close to the end of 'stp'. However, the Agrif_Update_Dyn routine which updates sshn for the parent domain is still called from within dyn_nxt, hence before sshn is actually updated from ssha in the child domain. Therefore, a time lag is introduced in the AGRIF updating process (minor bug). The call to Agrif_Update_Dyn should therefore be moved to ssh_nxt, possibly the AGRIF calls relevant to the one way coupling for the dynamics as well.

I will correct myself here. Above the "AGRIF calls relevant to the one way coupling for the dynamics" I was referring to is actually 'Agrif_dyn'. It is fine where it is now as it works on the ua/va arrays. In Agrif_dyn there are however lines like 'sshn(2,:)=sshn(3,:)' which might be more relevant in terms of ssha since the ssh arrays have not been switched in preparation for the next time-step (ssh_nxt).
