wifi: ath12k: avoid call ath12k_dp_mon_parse_rx_dest_tlv() for WCN7850

WCN7850 doesn't have RX MON component. So it's monitor mode design is
quite different from AP based chips like QCN9274, which have RX MON
component.

ath12k_dp_mon_parse_rx_dest_tlv() is such a specific function for AP based
chips.

So don't call this function for WCN7850.

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