Simplifications in procedure albsno. Since veget(:, 2:) was 0,
iterations 2 to nvm of the loop computing alb_neig_grid were useless.

Useless initializations of alb_neige in procedure interfsurf_hq:
alb_neig is always computed by albsno just before being used. Useless
computation of local variable zfra in the land ice case.
