[tor-commits] [tor/master] Don't choose exit nodes without desc available

[nickm@xxxxxxxxxxxxxx]

commit 47a2e5a9ce4b9324931781c76f3aa11f4d9ea0a2
Author: Sebastian Hahn <sebastian@xxxxxxxxxxxxxx>
Date:   Sat Apr 30 13:27:47 2011 +0200

    Don't choose exit nodes without desc available
    
    n_supported[i] has a random value prior to initialization, so a node
    that doesn't have routerinfo available can have a random priority.
    
    Patch contributed by wanoskarnet from #tor. Thanks!
