    Fix 8833: crash bug from using NULL node->ri in dirserv.c
    
    It appears that moria1 crashed because of one instance of this (the
    one in router_counts_toward_thresholds).  The other instance I fixed
    won't actually have broken anything, but I think it's more clear this
    way.
    
    Fixes bug 8833; bugfix on 0.2.4.12-alpha.
