Kaige Fu 29b7aff59f HV: Use NMI-window exiting to address req missing issue 
There is a window where we may miss the current request in the
notification period when the work flow is as the following:

      CPUx +                   + CPUr
           |                   |
           |                   +--+
           |                   |  | Handle pending req
           |                   <--+
           +--+                |
           |  | Set req flag   |
           <--+                |
           +------------------>---+
           |     Send NMI      |  | Handle NMI
           |                   <--+
           |                   |
           |                   |
           |                   +--> vCPU enter
           |                   |
           +                   +

So, this patch enables the NMI-window exiting to trigger the next vmexit
once there is no "virtual-NMI blocking" after vCPU enter into VMX non-root
mode. Then we can process the pending request on time.
