Yonghua Huang 3c119e124a check validity of 'VM-exit Int-Info' before extracting vector ...

1. exception vector and other information
   can be extracted from 'VM-Exit Interrupt-Information'
   field of VMCS only if bit31 (Valid) is set.
   -Intel SDM 24.9.2, Vol3

2.  Rename 'exit-interrupt_info' to 'idt_vectoring_info'
    in 'struct vcpu_arch', which is consistent with
    SDM 24.9.3, Vol3

3. 'IDT-vectoring information' in VMCS is 32bit
    -Intel SDM 24.9.3, Vol3

    Update the type of 'idt_vectoring_info' in
    'struct vcpu_arch'from 'uint32_t' to 'uint64_t'.
