vdpa_sim: clear pending_kick on device reset
vdpasim_kick_vq() sets pending_kick when a virtqueue is kicked while
the device is suspended (!running but DRIVER_OK). vdpasim_resume()
later replays kicks for all virtqueues when pending_kick is set.
vdpasim_do_reset() clears running and status but leaves pending_kick
unchanged. If a kick is deferred during suspend and the device is
reset before resume, a later resume can spuriously kick every
virtqueue even though no new work was queued after reset.
Clear pending_kick in vdpasim_do_reset() together with the other
device state that must not survive a reset.
