decrement Connections
Decrements connections from the provided inetAddress. This function is called when a channel handler is unregistered in Netty. Whenever a handler switches from one to another, the old one will be unregistered first, before the new one is registered. An example of this is moving from login to JS5. The exact flow is:
Register login
Unregister login
Register JS5
Unregister JS5
Parameters
inet Address
the address to decrement a connection from.
