cpufreq: intel_pstate: Update pid_params.sample_rate_ns in pid_param_set()
[ Upstream commit 6e7408acd04d06c04981c0c0fb5a2462b16fae4f ]
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: a4675fbc4a7a (cpufreq: intel_pstate: Replace timers with utilization update callbacks)
