QueueManager.disconnect() throws exception on disconnect failure

[andrewkirillov-ibm]

Here is scenario how to reproduce:

• Open connection a queue manager, keep it;
• Go to your queue manager and stop it, so that connection get broken;
• Close connection in the Python app.

It will cause exception:

Exception ignored in: <function QueueManager.__del__ at 0x7f3134006d40>
Traceback (most recent call last):
  File "/home/akirillo/mqgit/agents/mq-agents/src/mq-mcp-server/.venv/lib/python3.13/site-packages/ibmmq/mqqmgr.py", line 64, in __del__
    self.disconnect()
  File "/home/akirillo/mqgit/agents/mq-agents/src/mq-mcp-server/.venv/lib/python3.13/site-packages/ibmmq/mqqmgr.py", line 408, in disconnect
    mqlog.trace_exit("qmgr:disconnect", ep=2, rc=rv[2])
IndexError: tuple index out of range

The problem is that rv tuple has 2 values - COMP code and REASON. But the code does rv[2], which is out of range.

mqlog.trace_exit("qmgr:disconnect", ep=2, rc=rv[2])

Thanks for finding that. I'll fix it for the next release.

But remember that in this scenario, you should still be getting an exception that you need to deal with: MQRC_CONNECTION_BROKEN
