RFR: 8175131: sun.rmi.transport.tcp.TCPChannel.createConnection close connection on timeout

[Rob McKenna]

Hi folks,

Looking for a review of the following simple change:

https://bugs.openjdk.java.net/browse/JDK-8175131
http://cr.openjdk.java.net/~robm/8175131/webrev.01/

Note: I've deliberately limited the connection closure to the described
case. If however you feel that it should be applied generally when an
exception is thrown (in the if and / or else block) let me know!
