Eduardo Habkost 40e80ee411 i386/kvm: Blacklist TSX on known broken hosts ...

Some Intel CPUs are known to have a broken TSX implementation. A
microcode update from Intel disabled TSX on those CPUs, but
GET_SUPPORTED_CPUID might be reporting it as supported if the
hosts were not updated yet.

Manually fixup the GET_SUPPORTED_CPUID data to ensure we will
never enable TSX when running on those hosts.
