Yury Norov 01bb11ad82 sched/topology: fix KASAN warning in hop_cmp() 
Despite that prev_hop is used conditionally on cur_hop
is not the first hop, it's initialized unconditionally.

Because initialization implies dereferencing, it might happen
that the code dereferences uninitialized memory, which has been
spotted by KASAN. Fix it by reorganizing hop_cmp() logic.
