Reset server_socket_ when listen fails in extensions::TCPSocket.

Reset server_socket_ when listen fails in extensions::TCPSocket.

net::TCPServerSocket::Listen will close its internal socket if it fails
to bind and begin listening. This leaves the extensions socket object in
a bad state. Instead reset the socket so that an application can try to
bind it again.
