Commit Message

Currently, when ath12k retrieves values from the structure
rx_msdu_end_wcn7850, the information obtained is incorrect. This is because
the definition of the rx_msdu_end_wcn7850 structure in ath12k is incorrect.
In fact, the rx_msdu_end structure used by WCN7850 is the same as the
rx_msdu_end structure of QCN9274.

Commit ed823fd113b7 ("wifi: ath12k: add msdu_end structure for WCN7850")
introduced this structure. The original issue trying to be fixed with that
commit is that the TID information retrieved from the rx_msdu_end structure
was incorrect, and it was thought that the structure wasn't correct, so a
supposedly correct structure was introduced. However it was subsequently
discovered that the TID information is only guaranteed to be valid in the
rx_msdu_start structure, so that commit added the logic to retrieve the TID
from the rx_msdu_start, but unfortunately kept the rx_msdu_end_wcn7850
structure.

To address this issue, revert the code related to the rx_msdu_end_wcn7850
structure, retaining the TID retrieval logic.

This patch does not affect QCN9274.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
