Bluetooth: Fix memory leak at end of hci requests
In hci_req_sync_complete the event skb is referenced in hdev->req_skb.
It is used (via hci_req_run_skb) from either __hci_cmd_sync_ev which will
pass the skb to the caller, or __hci_req_sync which leaks.
unreferenced object 0xffff880005339a00 (size 256):
