wifi: ath12k: Fix peer lookup in ath12k_dp_mon_rx_deliver_msdu()

Browse source

[ Upstream commit 7ca61ed8b3 ]

In ath12k_dp_mon_rx_deliver_msdu(), peer lookup fails because
rxcb->peer_id is not updated with a valid value. This is expected
in monitor mode, where RX frames bypass the regular RX
descriptor path that typically sets rxcb->peer_id.
As a result, the peer is NULL, and link_id and link_valid fields
in the RX status are not populated. This leads to a WARN_ON in
mac80211 when it receives data frame from an associated station
with invalid link_id.

Fix this potential issue by using ppduinfo->peer_id, which holds
the correct peer id for the received frame. This ensures that the
peer is correctly found and the associated link metadata is updated
accordingly.
