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.
