sshproxy: keep addr and free it on close.

Browse Source 
The caller of new_connection has relinquished ownership of the
SockAddr it passes in. So the receiver of that SockAddr must remember
to free it, or else we leak memory.

(Additionally, this means SshProxy will be able to remember the
address during its run, e.g. to use in calls to its Plug. But that's
not implemented yet.)
