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.
