Move logic that determines whether to use JDK serialization after getInnerChannel to account for PA interceptor

[cwperks]

Description

Performance Analyzer (PA) sets up a transport interceptor that wraps a TransportChannel. The security plugin has logic to extract the inner channel so that the rest of SecuritySSLRequestHandler uses the original channel. There is logic before the inner channel extraction to determine whether to use JDK Serialization if the incoming message was received from a node running OS <= 2.10. That code relies on channel.getVersion() to get the version of the node that transmitted the transport request, but when the channel is wrapped its not delegating to the original channel in PA. This PR moves the logic after the extraction of the inner channel to ensure that channel.getVersion() correctly returns the version from the transmitting node.
