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.
