    KVM: VMX: Reset mmu context when entering real mode
    Resetting an SMP guest will force AP enter real mode (RESET) with
    paging enabled in protected mode. While current enter_rmode() can
    only handle mode switch from nonpaging mode to real mode which leads
    to SMP reboot failure.
    Fix by reloading the mmu context on entering real mode.
