htb: fix two bugs

Commit 56b765b79e9 (htb: improved accuracy at high rates)
introduced two bugs :

1) one bstats_update() was inadvertently removed from
   htb_dequeue_tree(), breaking statistics/rate estimation.

2) Missing qdisc_put_rtab() calls in htb_change_class(),
   leaking kernel memory, now struct htb_class no longer
   retains pointers to qdisc_rate_table structs.

   Since only rate is used, dont use qdisc_get_rtab() calls
   copying data we ignore anyway.
