sch: add missing u64 in psched_ratecfg_precompute()
It seems that commit

sch: make htb_rate_cfg and functions around that generic
adds little regression.
Before:
# tc qdisc add dev eth0 root handle 1: htb default ffff
# tc class add dev eth0 classid 1:ffff htb rate 5Gbit
# tc -s class show dev eth0
class htb 1:ffff root prio 0 rate 5000Mbit ceil 5000Mbit burst 625b cburst
625b

rate 0bit 0pps backlog 0b 0p requeues 0

After:
# tc qdisc add dev eth0 root handle 1: htb default ffff
# tc class add dev eth0 classid 1:ffff htb rate 5Gbit
# tc -s class show dev eth0
class htb 1:ffff root prio 0 rate 1544Mbit ceil 1544Mbit burst 625b cburst
625b
Sent 5073 bytes 41 pkt (dropped 0, overlimits 0 requeues 0)
rate 1976bit 2pps backlog 0b 0p requeues 0

This probably due to lost u64 cast of rate parameter in
psched_ratecfg_precompute() (net/sched/sch_generic.c).
