netem: fix gemodel loss generator
Patch from developers of the alternative loss models, downloaded from:
http://netgroup.uniroma2.it/twiki/bin/view.cgi/Main/NetemCLG
"in case 2, of the switch we change the direction of the inequality to
net_random()>clg->a3, because clg->a3 is h in the GE model and when h
is 0 all packets will be lost."
