iwlwifi: control led while update tx/rx bytes counts

LED blinking rate is based on tx/rx traffic, the most reasonable place
to do it is after update the traffic byte counts

This fixes the recent LED blinking breakage on 3945 introduced by "iwlwifi:
separate led function from statistic notification"
