Rex LuandFelix Fietkau c73ffc4a2e wifi: mt76: check txfree done event on the WED hw path
Check the txfree done event DW1 bit 15 when WED is enabled, to avoid
the driver reading a txfree done event before WED has finished reading
it. No need to check this flag on WED v2, otherwise SER will occur.

The bit position was previously defined as MT_DMA_CTL_BURST, which is
unused; rename it to match its function on the txfree ring.
