Avi Kivity 4d56c8a787 KVM: VMX: Only save/restore MSR_K6_STAR if necessary ...

Intel hosts only support syscall/sysret in long more (and only if efer.sce
is enabled), so only reload the related MSR_K6_STAR if the guest will
actually be able to use it.

This reduces vmexit cost by about 500 cycles (6400 -> 5870) on my setup.
