FUNCTION WDA_DS_GetFrameTypeSubType
DESCRIPTION
Get typeSubtype from the packet. The BD header should have this.
But some reason, Libra/Volans read it from 802.11 header and save it
back to BD header. So for NON integrated SOC, this function does
the same.
For integrated SOC, WDI does the same, not TL.
It does return typeSubtype from RX meta info for integrated SOC.
