[PATCH v5 08/11] wifi: ath12k: fix incorrect logic of calculating vdev_stats_id

[Kang Yang]

During calculate vdev_stats_id, will compare vdev_stats_id with
ATH12K_INVAL_VDEV_STATS_ID by '<='. 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.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
Fixes: d889913205cf ("wifi: ath12k: driver for Qualcomm Wi-Fi 7 devices")
