chao.an 8ae8c10954 net/poll: fix race condition if connect free before poll teardown

Net poll teardown is not protected by net lock, if the conn is released
before teardown, the assertion failure will be triggered during free dev
callback, this patch will add the net lock around net poll teardown to
fix race condition
