Bluetooth: Ignore completed packets events for unknown connections
Bluetooth: Ignore completed packets events for unknown connections

Some controllers are broken in that they may send a completed packets
event after a disconnection has already occurred and the handle is
invalid:

> HCI Event: Disconnect Complete (0x05) plen 4
        Status: Success (0x00)
        Handle: 64
        Reason: Remote User Terminated Connection (0x13)
< HCI Command: LE Set Advert.. (0x08|0x000a) plen 1
        Advertising: Enabled (0x01)
> HCI Event: Command Complete (0x0e) plen 4
      LE Set Advertise Enable (0x08|0x000a) ncmd 1
        Status: Success (0x00)
> HCI Event: Number of Completed Pa.. (0x13) plen 5
        Num handles: 1
        Handle: 64
        Count: 1

Since the disconnection code already takes care of updating the
le_pkts_sem semaphore appropriately there is no need to do anything
for this kind of events (except log a warning of a misbehaving
controller).
