vmxnet3: set RX interrupt pending only when needed
When an RX thread handles more than one RX queue and has a mix of
queues in interrupt mode and polling mode, the RX input routine is
naturally in polling mode. In that case, there is no need to set RX
interrupt pending when descriptor is available in the queue for
interrupt mode.
Type: fix
