[PATCH V3 3/6] vDPA: implement vq IRQ allocate/free helpers in vDPA core
...ter producer when DRIVER_OK and unregister producer when
!DRIVER_OK in vhost-vDPA
3) deal with the synchronization with SET_VRING_CALL
4) document that irq is not expected to be changed during DRIVER_OK
This can make sure the API works during driver probe, and we don't need
the setup_irq and unsetup_irq method in vdpa_driver
Thanks
