wifi: mt76: fix uninitialised RXDMAD_C descriptor info
Unlike other WED-RRO queues, RXDMAD_C frames continue into the skb build
path, but mt76_dma_get_buf() skips the desc->info read for RRO queues, so
the uninitialised on-stack info was stored into skb->cb and passed to
rx_skb(); initialise it to zero.
