wifi: ath12k: fix array out-of-bound access in SoC stats

In the Linux kernel, the following vulnerability has been resolved:

wifi: ath12k: fix array out-of-bound access in SoC stats

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.
