Commit 4b9852f4 ("KVM: x86: Fix INIT signal handling in various CPU states") fixed KVM to also latch pending LAPIC INIT event when vCPU is in VMX operation. However, current API of KVM_SET_MP_STATE allows userspace to put vCPU into KVM_MP_STATE_SIPI_RECEIVED or KVM_MP_STATE_INIT_RECEIVED even when vCPU is in VMX operation. Fix this by introducing a util method to check if vCPU state latch INIT signals and use it in KVM_SET_MP_STATE handler.
