ath10k: protect ath10k_htt_rx_ring_free with rx_ring.lock [ Upstream commit 168f75f11fe68455e0d058a818ebccfc329d8685 ] While debugging driver crashes related to a buggy firmware crashing under load, I noticed that ath10k_htt_rx_ring_free could be called without being under lock. I'm not sure if this is the root cause of the crash or not, but it seems prudent to protect it. Originally tested on 4.16+ kernel with ath10k-ct 10.4 firmware running on 9984 NIC.
