If vdev_stats_id is relatively small, then assign ATH12K_INVAL_VDEV_STATS_ID to vdev_stats_id. This logic is incorrect. Firstly, should use '>=' instead of '<=' to check if this u8 variable exceeds the max valid range. Secondly, should use the maximum value as comparison value. Correct comparison symbols and use the maximum value ATH12K_MAX_VDEV_STATS_ID for comparison.
