[COMMIT master] KVM: x86: fix CR8 handling

From: Andre Przywara andre.przyw...@amd.com The handling of CR8 writes in KVM is currently somewhat cumbersome. This patch makes it look like the other CR register handlers and fixes a possible issue in VMX, where the RIP would be incremented despite an injected #GP. Signed-off-by: Andre
