KVM: x86/pmu: Require nr fixed_pmc_events to match nr max fixed counters
Assert that the number of known fixed_pmc_events matches the max number of
fixed counters supported by KVM, and clean up related code.
Opportunistically extend setup_fixed_pmc_eventsel()'s use of
array_index_nospec() to cover fixed_counters, as nr_arch_fixed_counters is
set based on userspace input (but capped using KVM-controlled values).
