This way, we cannot directly call hci_do_le_scan() to scan LE devices in start_discovery(). To overcome this issue a derefered work (hdev->le_scan) was created so we can properly call hci_do_le_scan(). The helper function hci_le_scan() simply set LE scan parameters and queue hdev->le_scan work. The work is queued on system_long_wq since it can sleep for a few seconds in the worst case (timeout).
