[PATCH ath-next] wifi: ath12k: Pass the correct value of each TID during a stop AMPDU session

[Reshma Immaculate Rajkumar <reshma.rajkumar@oss.qualcomm.com>]

With traffic ongoing for data TID [TID 0], an ADDBA request to
stop AMPDU for the BA session was received on management TID [TID 4].
The corresponding TID number was incorrectly passed to stop the BA session,
resulting in the BA session for data TIDs being stopped and the BA size
being reduced to 1, causing an overall dip in TCP throughput.

Fix this issue by passing the correct argument from
ath12k_dp_rx_ampdu_stop() to ath12k_dp_arch_peer_rx_tid_reo_update()
during an AMPDU stop session. Instead of passing peer->dp_peer->rx_tid,
which is the base address of the array, corresponding to TID 0, pass
the value of &peer->dp_peer->rx_tid[params->tid]. With this, the
different TID numbers are accounted for.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.5-01651-QCAHKSWPL_SILICONZ-1
