Fix advertised packet scheduler timer resolution
patch 3c0cfc135829b98f7a4894938652f9ef78e24237 in mainline
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.
