Seems there is a bug around dht xlator when add bricks because race condition
when dht use conf->subvolume_cnt to start a for loop.like this:

local->call_cnt = conf->subvolume_cnt; //would be changed when add bricks
for (i = 0; i < conf->subvolume_cnt; i++) {
    STACK_WIND_COOKIE (frame, dht_selfheal_dir_mkdir_lookup_cbk...
}
