With buf uninitialized in mt76_dma_tx_queue_skb_raw, its field skip_unmap

If this happens, it will cause DMA mappings for MCU command frames to not be

BSS_INFO_BASIC is never called alone with inactive state, which always
follows beacon offload disable, so keep it enabled throughout interfaces
life cycle. Inactive state also removes sta record of all connected
stations, thurs causes connection lost which defeats the purpose of CSA.

Lastly, this is especially an unexpected behavior that keeping mt7622
