dht/tier/rebalancer: Fix reset of tiering client pid

In the patch http://review.gluster.org/#/c/9657
the client pid set by tiering migration was getting over-
written in dht_start_rebalance_task(). Just corrected it
in dht_setxattr() before calling dht_start_rebalance_task()
and removed it from dht_start_rebalance_task().
