Get Exception when destroying an XD syslog-tcp source i.e. int-syslog:inbound-channel-adapter [INT-3473]

[spring-operator]

Glenn Renfro opened INT-3473 and commented

Not a critical bug.

However, when destroying the syslog-tcp the following exception is thrown:

19:06:32,569 ERROR pool-96-thread-1 connection.TcpNioServerConnectionFactory - Selector closed

We're canceling the selector before resetting the active flag so the exception is logged.

Merged and cherry-picked.
