Sometimes TX/RX pkt statistics workqueue may be delayed.
The workqueue interval value is pre-defined and is used
for bandwidth vote. If the interval is inaccurate, whole
pkts statistics are not accurate, bus bandwidth vote is
wrong also. This change is aimed to use absolute workqueue
time delay instead of pre-defined value to get accurate
packets per milliseconds result.
