…ck to avoid deadlock Fix a potential deadlock between PingChannel and PingCheckMgr. This patch changes sendNext() to: - Release the channel lock before calling next_to_send_cb_. - Reacquire the lock afterward and re-check canSend() before proceeding. - Keep setting `sending_` inside the locked region to ensure only one send path is active at a time.
