iso bind for slave not working as intended

[Thalley]

Describe the bug
In the ISO shell, there's an iso bind command that binds an ISO with a ACL connection. This also sets the QOS parameters (the CIG parameters). The issue is that the bind needs to be done on both the master and slave, but the QOS parameters should only be done for the master (in fact, the command will always fail for the slave).

Furthermore, in case that the command does fail, it changes the state of the ISO channel. I suppose that errors should revert any changes?

To Reproduce
Steps to reproduce the behavior:

1. Establish connection between master and slave using the BT audio_shell
2. Call iso bind on the slave and see that it fails

Expected behavior
Expected that the iso bind command will successfully return after binding the ISO on the slave, and not attempt to set any QOS parameters.

Impact
Since the bind will happen, even with the error, the command can still be used.

Logs and console output

Additional context
It has been discussed that setting the QOS parameters should be removed from iso bind and moved to a new command for the master. Alternatively, the command could/should check if the ISO is a master or slave, and act accordingly (i.e. iso bind for slave should just bind and not set parameters).
