x86: fix typo in filter_cpuid_features()
Impact: fix wrong disabling of cpu features an amd system got this strange output: CPU: CPU feature monitor disabled due to lack of CPUID level 0x5 but in /proc/cpuinfo I have: cpuid level : 5 on intel system: CPU: CPU feature monitor disabled due to lack of CPUID level 0x5 CPU: CPU feature dca disabled due to lack of CPUID level 0x9 but in /proc/cpuinfo i have: cpuid level : 11 Tt turns out there is a typo, and we should use level member in df.
