In ath12k_dp_rx_h_mpdu(), during the undecap to native wifi mode, the rx descriptor memory is overwritten. After this function call, any subsequent accesses to rx descriptor related memory yield invalid values. Fix this by replacing instances where rx_desc was used with the pre-cached information in rx_info. This ensures that the values populated from the rx descriptor are accurate and prevents invalid memory access.
