Avoid assertion on nonblocking connect()
From: Christian Prochaska <christian.prochaska@genode-labs.com>
When calling 'connect()' in nonblocking mode and the connection has been
established, don't call 'tcp_connect()' again, which would trigger an
assertion with the message 'tcp_connect: can only connect from state
CLOSED'.
