[PATCH] ipvs: Make wrr "no available servers" error message rate-limited

[Sven Wegener]

No available servers is more an error message than something informational. It
should also be rate-limited, else we're going to flood our logs on a busy
director, if all real servers are out of order with a weight of zero.

Actually, do we need this message at all? The wrr scheduler is the only one
printing an error message in such a case.
