Typo in acceptor configuration for Netty Servlet

Title: Configuring Netty Servlet

Describe the issue:
EAP 6.4 Admin Guide - Section 18.2.5. Configuring Netty Servlet

In the sample acceptor configuration, the "use-servlet" param is invalid. Instead it should be "use-invm".

The acceptor configuration example should be:
<acceptors>
<acceptor name="netty-servlet">
<factory-class>
org.hornetq.core.remoting.impl.netty.NettyAcceptorFactory
</factory-class>
<param key="use-invm" value="true"/>
<param key="host" value="org.hornetq"/>
</acceptor>
</acceptors>
