Sean Christopherson 17a024a8b9 KVM: x86: Refresh PMU after writes to MSR_IA32_PERF_CAPABILITIES 
Refresh the PMU if userspace modifies MSR_IA32_PERF_CAPABILITIES.  KVM
consumes the vCPU's PERF_CAPABILITIES when enumerating PEBS support, but
relies on CPUID updates to refresh the PMU.  I.e. KVM will do the wrong
thing if userspace stuffs PERF_CAPABILITIES _after_ setting guest CPUID.

Opportunistically fix a curly-brace indentation.

Fixes: c59a1f106f ("KVM: x86/pmu: Add IA32_PEBS_ENABLE MSR emulation for extended PEBS")
