wifi: ath12k: Use HTT_TCL_METADATA_VER_V1 in FTM mode

Browse Source 
Currently host sends HTT_TCL_METADATA_VER_V2 to the firmware
regardless of the operating mode (Mission or FTM).

Firmware expects additional software information (like peer ID, vdev
ID, and link ID) in Tx packets when HTT_TCL_METADATA_VER_V2 is set.
However, in FTM (Factory Test Mode) mode, no vdev is created on the
host side (this is expected). As a result, the firmware fails to find
the expected vdev during packet processing and ends up dropping
packets.

To fix this, send HTT_TCL_METADATA_VER_V1 in FTM mode because FTM
mode doesn't support HTT_TCL_METADATA_VER_V2.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.5-01651-QCAHKSWPL_SILICONZ-1
