KVM: x86: believe what KVM says about WAITPKG
Currently, QEMU is overriding KVM_GET_SUPPORTED_CPUID's answer for
the WAITPKG bit depending on the "-overcommit cpu-pm" setting. This is a
bad idea because it does not even check if the host supports it, but it
can be done in x86_cpu_realizefn just like we do for the MONITOR bit.
This patch moves it there, while making it conditional on host
support for the related UMWAIT MSR.
