remove compiler warnings for CICE; fix missing j-loop index (#75) (#944)

* fix dummy arguments w/o values
* fix missing j-loop in export 4d

Resolve compiler warning arising from ice_prescribed_mod due to the intent(out) variable RC not being given an explicit value. This is an operational requirement for NOAA. Fix bug arising from missing j-loop index in ice_import_export
