KVM: SVM: Ensure SPEC_CTRL[63:32] is context switched between guest and host
SPEC_CTRL is an MSR, i.e. a 64-bit value, but the VMRUN assembly code
assumes bits 63:32 are always zero. The bug is _currently_ benign because
neither KVM nor the kernel support setting any of bits 63:32, but it's
still a bug that needs to be fixed.
