[PATCH v4 7/8] mt76: mt7915: set VTA bit in tx descriptor

[Shayne Chen]

The VTA (Valid for Txd Arrival time) bit should be set in tx descriptor,
which is necessary for WM fw to schedule SPL (station priority list)
normally before generating txcmd.
If it's not set, some unexpected wcids may be involved in SPL.
