Don't expect LB call to be NULL inside LB call retry timer.

The timer callback runs independently of query_for_backends_locked()
(which initializes the LB call). It's possible for the timer callback to
fire right after query_for_backends_locked() has initialized the LB
call. These changes makes the timer cb be a no-op in that scenario.
