wl18xx: limit Tx for the AP single-STA-in-PSM case
Treat a single connected STA in PSM as a slow link and regulate Tx speed according to slow link priority/stop thresholds. This allows us to avoid flooding the FW, while delivering decent throughput to a peer in forced-PSM. [Small simplification of the if statements -- Luca] Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
