ipvs: Put backup thread on mcast socket wait queue
Instead of doing an endless loop with sleeping for one second, we now put the backup thread onto the mcast socket wait queue and it gets woken up as soon as we have data to process. Signed-off-by: Sven Wegener <sven.wegener@stealer.net> Acked-by: Simon Horman <horms@verge.net.au>
