[PATCH ath-current] wifi: ath11k: fix wrong TID passed when stopping AMPDU session

When handling a DELBA request, ath11k_dp_rx_ampdu_stop() calls
ath11k_peer_rx_tid_reo_update() to tear down the BA session for the
specified TID. However, it currently passes peer->rx_tid instead of the
entry corresponding to params->tid.

Since peer->rx_tid is an array, this decays to a pointer to the first
element, effectively operating on TID 0 regardless of the TID in the
DELBA request. As a result, the BA session for TID 0 is stopped while
the intended TID remains active.

This leads to incorrect BA session state and may significantly reduce
RX throughput, as traffic that should use aggregation falls back to a
BA window size of 1 on TID 0.

Fix this by passing the correct TID entry:
   &peer->rx_tid[params->tid]
