cpufreq: intel_pstate: Update pid_params.sample_rate_ns in pid_param_set()
[ Upstream commitsteinar/wifi_calib_4_9_kernel6e7408acd0
] Fix the debugfs interface for PID tuning to actually update pid_params.sample_rate_ns on PID parameters updates, as changing pid_params.sample_rate_ms via debugfs has no effect now. Fixes:a4675fbc4a
