There is a race condition if we call this function in the
polling mode when running with multi-cores, same as other
places where the function is called, we only kick controller
in interrupt mode, also in `vfio_user_ctrlr_intr`,
`ctrlr->sqs[0]` may be set to NULL after the controller
poll call, so return earlier for this case.
