htb: report overhead attribute 

"tc class show dev ..." omits the overhead attribute for HTB.

After patch I have :

tc class add dev $DEV parent 1: classid 1:1 est 1sec 4sec htb \
    rate 12Mbit mtu 1500 quantum 1514 overhead 20

tc class show dev $DEV
class htb 1:1 root prio 0 rate 12000Kbit overhead 20 ceil 12000Kbit
burst 1500b cburst 1500b
