Bluetooth: Fix potential memory leak
If command is added to req then it should be freed in case if hdev is down or HCI_ADVERTISING flag is set. This introduces a helper in hci_request to purge the cmd_q to make cmd_q internal to hci_request which is used to fix the leak. This also replace accessing of cmd_q in hci_conn with the new helper.
