ath9k: fix transmitting to stations in dynamic SMPS mode
When transmitting to a receiver in dynamic SMPS mode, all transmissions that use multiple spatial streams need to be sent using CTS-to-self or RTS/CTS to give the receiver's extra chains some time to wake up. This fixes the tx rate getting stuck at <= MCS7 for some clients, especially Intel ones, which make aggressive use of SMPS. Signed-off-by: Felix Fietkau <nbd@nbd.name>
