Bluetooth: hci_sync: Fix handling of HCI_QUIRK_STRICT_DUPLICATE_FILTER

When HCI_QUIRK_STRICT_DUPLICATE_FILTER is set LE scanning requires
periodic restarts of the scanning procedure as the controller would
consider device previously found as duplicated despite of RSSI changes,
but in order to set the scan timeout properly set le_scan_restart needs
to be synchronous so it shall not use hci_cmd_sync_queue which defers
the command processing to cmd_sync_work.
