JChannelFactory not passing ref to protocol to JMX wrapper object

The AS JChannelFactory is not passing a ref to the underlying JGroups protocol instance to the org.jgroups.jmx package wrapper object it registers in JMX.

As a result, If you go into the jmx-console and look at any of the mbeans in the jboss.jgroups domain with type=protocol, all of the attribute values are "javax.management.RuntimeMBeanException"

Simple, fix, just add the required call to the wrapper object's attachProtocol method.
