Protect the common Espressif Wi-Fi netdev RX queue with a spinlock. The Wi-Fi RX callback enqueues packets while the netdev upper-half RX thread dequeues them, and the IOB queue helpers are not internally serialized. Under sustained receive traffic that race can corrupt the queue state, strand IOBs, and degrade throughput over time as reported in issue #16915. Initialize the lock during device setup and use it when clearing the queue on ifup, enqueueing received packets, and dequeuing them for the upper half.
