From: Alain Michaud <alainm@xxxxxxxxxxxx>
If a hardware error occurs and the connections are flushed without a
disconnection_complete event being signaled, the temporary linkkeys are
not flushed.
This change ensures that any outstanding flushable linkkeys are flushed
when the connection are flushed from the hash table.
