* This function can be used to update a CIG. It will update the group specific
* parameters, and, if supplied, change the QoS parameters of the individual
* CIS. If the cis_channels in @p param contains CIS that was not originally
* in the call to bt_iso_cig_create(), these will be added to the group.
* It is not possible to remove any CIS from the group after creation.
*
* This can be called at any time before connecting an ISO to a remote device.
* Once any CIS in the group has connected, the group cannot be changed.
*
* Once a CIG is created, the channels supplied in the @p param can be
* connected using bt_iso_chan_connect.
*
* @param cig Connected Isochronous Group object.
* @param param The parameters used to reconfigure the CIG.
*
* @return 0 in case of success or negative value in case of error.
