sfc: Make queue flushes more reliable
Increase the potential retry count for RX flushes from 5 to 100.
Stop polling the RX_DESC_PTR_TBL to infer that a flush might have
happened. Instead absolutely rely on the flush events, unless bug 7803
applies (Falcon rev A only).
To keep things quick, request flushes for every TX and RX queue up
front, and match up the events to requests.
