[NET_SCHED]: Show timer resolution instead of clock resolution in /proc/net/psched 

The fourth parameter of /proc/net/psched is supposed to show the timer
resultion and is used by HTB userspace to calculate the necessary
burst rate. Currently we show the clock resolution, which results in a
too low burst rate when the two differ.
