Frederic Dalleau 9afee94939 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):
  comm "kworker/u3:1", pid 1011, jiffies 4294671976 (age 107.389s)
