x86: warn of incorrect cpu_khz on AMD systems
Impact: add debug check
If none of the perfctrs are free when calculating cpu_khz we default to
using ctr 3 (ie, we just choose 3). This may lead to an incorrect tsc
freq value which can cause the system to be unstable.
To aid in future debugging, WARN the user of a potential problem.
