wifi: ath12k: fix array out-of-bound access in SoC stats
[ Upstream commit e106b7ad13c1d246adaa57df73edb8f8b8acb240 ]
Currently, the ath12k_soc_dp_stats::hal_reo_error array is defined with a
maximum size of DP_REO_DST_RING_MAX. However, the ath12k_dp_rx_process()
function access ath12k_soc_dp_stats::hal_reo_error using the REO
destination SRNG ring ID, which is incorrect. SRNG ring ID differ from
normal ring ID, and this usage leads to out-of-bounds array access. To
fix this issue, modify ath12k_dp_rx_process() to use the normal ring ID
directly instead of the SRNG ring ID to avoid out-of-bounds array access.
