KVM: x86: emulator: update the emulation mode after CR0 write ...
commit ad8f9e69942c7db90758d9d774157e53bce94840 upstream.
Update the emulation mode when handling writes to CR0, because
toggling CR0.PE switches between Real and Protected Mode, and toggling
CR0.PG when EFER.LME=1 switches between Long and Protected Mode.
This is likely a benign bug because there is no writeback of state,
other than the RIP increment, and when toggling CR0.PE, the CPU has
to execute code from a very low memory address.
