cxgb4: Stop Rx Queues before freeing it up
Stop all Ethernet RX Queues before freeing up various Ingress/Egress
Queues, etc. We were seeing cases of Ingress Queues not getting serviced
during the shutdown process leading to Ingress Paths jamming up through
the chip and blocking the shutdown effort itself.
One such case involved the Firmware sending a "Flush Token" through the
ULP-TX -> ULP-RX path for an Ethernet TX Queue being freed in order to
make sure there weren't any remaining TX Work Requests in the pipeline.
But the return path was stalled by Ingress Data unable to be delivered to
the Host because those Ingress Queues were no longer being serviced.
