For WCN7850, it doesn't have an RX MON component(RX MON dest ring and RX MON buffer ring). So it can only reuse the mon status ring, RX refill ring, and error dst ring for monitor mode. Every time the hardware captures a packet, it will store status information into the status ring and store the MSDU payload buffer address into the error dst ring. When host reaps the MSDU payload and consumes a buffer, it will replenish the RX refill ring to indicate a new buffer. The configuration of the error dst/RX ring already exists. But there is no configuration for mon status ring. So add ring configuration for it.
