[PATCH 3/3] wifi: ath12k: Refactor Rx status TLV parsing procedure argument

[Karthikeyan Periyasamy <quic_periyasa@xxxxxxxxxxx>]

Currently, ath12k_dp_mon_rx_parse_status_tlv() takes the TLV tag, TLV data
and TLV userid as separate arguments from the caller. These argument can
be fetched from the TLV header itself. Therefore, pass the TLV header and
retrieve the necessary fields from the header instead of passing them from
the caller.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
