wifi: ath12k: fix invalid AMPDU factor calculation in ath12k_peer_assoc_h_he()

Browse Source 
[ Upstream commit a66de2d0f22b1740f3f9777776ad98c4bee62dff ]

Currently ampdu_factor is wrongly calculated in ath12k_peer_assoc_h_he(), fix it.

This is found during code review.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4

Fixes: d889913205 ("wifi: ath12k: driver for Qualcomm Wi-Fi 7 devices")
