KVM: x86/pmu: Limit the maximum number of supported Intel GP counters
The Intel Architectural IA32_PMCx MSRs addresses range allows for a
maximum of 8 GP counters, and KVM cannot address any more. Introduce a
local macro (named KVM_INTEL_PMC_MAX_GENERIC) and use it consistently to
refer to the number of counters supported by KVM, thus avoiding possible
out-of-bound accesses.
