KVM: VMX: Introduce exit reason for receiving INIT signal on guest-mode



According to Intel SDM section 25.2 "Other Causes of VM Exits",
When INIT signal is received on a CPU that is running in VMX
non-root mode it should cause an exit with exit-reason of 3.
(See Intel SDM Appendix C "VMX BASIC EXIT REASONS")

This patch introduce the exit-reason definition.
