Problem at south pole when there is no ice

Description
When ORCHIDEE includes the south pole in coupled mode, the routing scheme fails because resolution(ib,1)=0. This problem has been reported by the group working with paleo simulations, by Sebastien Nguyen and Pierre Sepulchre.
Following versions of the code have been used:
LMDZ: LMDZ5/branches/IPSLCM5A2.1 revision 3907
ORCHIDEE: ORCHIDEE-IPSLCM5A2.1 revision 6596
This problem is only seen when the ice sheet over Antartic has been modified so there is no ice on the south pole.
A patch avoiding resolution(ib,1)=0 in routing.f90 has been tested by Sebastien Nguyen and will be commited on ORCHIDEE branch used.

Should this be done as well in ORCHIDEE_2_2 ? Maybe yes because it is in the routing scheme.

This problem appeared again with the trunk. In intersurf, the area is also calculated and needed to be corrected in the same way as done in above commit. This is done in the trunk here: [7785].
To consider if this needs to be done in the branch ORCHIDEE-IPSLCM5A2.1 as well.

A faire : tester la variable cell_area fourni par l'interface de LMDZ

Commit done in the branch ORCHIDEE-IPSLCM5A2.1 revision [7376].
A solution needs for the trunk as well. Do we keep the same solution ? It could also be possible to make a change further up, in intersurf or in LMDZ maybe.
