As the latest Intel 64 and IA-32 Architectures Software Developer's Manual, UMWAIT and TPAUSE instructions cause a VM exit if the RDTSC exiting and enable user wait and pause VM-execution controls are both 1. Because KVM never enable RDTSC exiting, the vm-exit for UMWAIT and TPAUSE should never happen. Considering EXIT_REASON_XSAVES and EXIT_REASON_XRSTORS is also unexpected VM-exit for KVM. Introduce a common exit helper handle_unexpected_vmexit() to handle these unexpected VM-exit.
