KVM: x86: nSVM: implement nested vGIF
In case L1 enables vGIF for L2, the L2 cannot affect L1's GIF, regardless of STGI/CLGI intercepts, and since VM entry enables GIF, this means that L1's GIF is always 1 while L2 is running. Thus in this case leave L1's vGIF in vmcb01, while letting L2 control the vGIF thus implementing nested vGIF. Also allow KVM to toggle L1's GIF during nested entry/exit by always using vmcb01.
