sched/walt: Update cpufreq_driver_fast_switch() invocation

Browse Source 
cpu_frequency trace events are coming twice when a frequency
switch happens. This is due to commit 08d8c65e84 ("cpufreq:
Move traces and update to policy->cur to cpufreq core") in the
upstream which takes care of cpu_frequency trace event and
updates to policy->cur when cpufreq_driver_fast_switch() is
called.

So remove the redundant code from waltgov cpufreq governor to
avoid duplicate cpu_frequency trave events.
