Srinivas Pandruvada 8e601a9f97 cpufreq: intel_pstate: Fix divide by zero on Knights Landing (KNL) 
This is a workaround for KNL platform, where in some cases MPERF counter
will not have updated value before next read of MSR_IA32_MPERF. In this
case divide by zero will occur. This change ignores current sample for
busy calculation in this case.

Fixes: b34ef932d7 (intel_pstate: Knights Landing support)
