KVM: VMX: Advertise CPU_BASED_RDPMC_EXITING for nested guests
Based on commit fee84b079d5ddee2247b5c1f53162c330c622902 upstream.
Intercept RDPMC and forward it to the PMU emulation code.
Newer vmx support will only allow to load the kvm_intel module
if RDPMC_EXITING is supported. Even without the actual support
this part of the change is required on 3.2 hosts.
