Bluetooth: ISO: use hci_sync for setting CIG parameters
When reconfiguring CIG after disconnection of the last CIS, LE Remove CIG shall be sent before LE Set CIG Parameters. Otherwise, it fails because CIG is in the inactive state and not configurable (Core v5.3 Vol 6 Part B Sec. 4.5.14.3). This ordering is currently wrong under suitable timing conditions, because LE Remove CIG is sent via the hci_sync queue and may be delayed, but Set CIG Parameters is via hci_send_cmd. Make the ordering well-defined by sending also Set CIG Parameters via hci_sync.
