wl12xx: Do end-of-transactions transfers only if needed
On newer hardware revisions, there is no need to write the host's counter at the end of a RX transaction. The same applies to writing the number of packets at the end of a TX transaction. It is generally a good idea to avoid unnecessary SDIO/SPI transfers. Throughput and CPU usage are improved when avoiding these. Send the host's RX counter and the TX packet count only if needed, based on the hardware revision.
