Maxim Mikityanskiy 2ba413da62 net/tls: Protect from calling tls_dev_del for TLS RX twice ... [ Upstream commit 025cc2fb6a ] tls_device_offload_cleanup_rx doesn't clear tls_ctx->netdev after calling tls_dev_del if TLX TX offload is also enabled. Clearing tls_ctx->netdev gets postponed until tls_device_gc_task. It leaves a time frame when tls_device_down may get called and call tls_dev_del for RX one extra time, confusing the driver, which may lead to a crash. This patch corrects this racy behavior by adding a flag to prevent tls_device_down from calling tls_dev_del the second time.
