Subject: [PATCH 1/1 v2] Bluetooth: make the balance of judgement condition to fix a false report
This patch is to balance the condition scope between hci_get_cmd_complete and
hci_event_packet about orig_skb as follows:
if (req_complete_skb || event == HCI_EV_CMD_STATUS ||
event == HCI_EV_CMD_COMPLETE)
orig_skb = skb_clone(skb, GFP_KERNEL);
And hci_get_cmd_complete will bt_dev_err out when HCI_EV_CMD_STATUS, so a lot
of asymmetric conditions are triggered. Since both of them are the entry into
hci_get_cmd_complete, we'd better get STATUS into judge the false out there.

v2: remove redundant braces and adjust the indentation.
Cheers,
