Fix tag len error for sta_rec_wtbl, which causes fw parsing error for
the tags placed behind it.
Fixes: e57b7901469f ("mt76: add mac80211 driver for MT7915 PCIe-based
chipsets")

For broadcast/multicast wcid, the muar_idx should be 0xe.

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.

Have you tested this in station mode? I tried merging this into my tree
and it broke station mode. Symptom was that it associated, but could not
get DHCP. It worked if I disabled AX mode and made it associate as 11ac.
I think root cause is probably that the beacon is never set in STA mode,
but the code building the MCU messages are unconditionally looking at
the values derived from the beacon caps when making decisions about bfer/bfee
and ldpc and such.
Thanks,
Ben
