dispatcher_request_failed: check if conn_data is not NULL

Trace attached on lp #392678 seems to indicate that the
priv->connections hash table doesn't have a ConnectionData associated
with the connection. A possible explanation could be that this
connection has been invalidated before the RequestChannel call is
terminated.

Check if ConnectionData so Empathy won't crash in such case.
