wifi: ath12k: fix TX and RX MCS rate configurations in HE mode
Currently, the TX and RX MCS rate configurations per peer are
reversed when sent to the firmware. As a result, RX MCS rates
are configured for TX, and vice versa. This commit rectifies
the configuration to match what the firmware expects.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
