Upstream keepalive: clearing of c->data in cached connections.

Previously, connections returned from keepalive cache had c->data
pointing to the keepalive cache item.  While this shouldn't be a problem
for correct code, as c->data is not expected to be used before it is set,
explicitly clearing it might help to avoid confusion.
