When a connection is interrupted during an async write, the callback
can attempt to close a handle that's already closing, causing:
handle 0x... is already closing
tcp.lua:161-162 correctly guards with is_closing():
if not client.tcp_handle:is_closing() then
client.tcp_handle:close()
end
But client.lua:219,223 was missing this guard. Added the same defensive
check to prevent the race condition.
