Revert "Wake WALSender to reduce data loss at failover for async commit."

Browse Source 
This reverts commit 090e8a984cf1a8a3ef7f6db6dc919f843902d80c.
Since WalSndWakeup does not exist in 9.0, it's clear that this patch
wasn't even compiled in this branch.  Perhaps some variant of it is
appropriate in 9.0, but for the moment I'm just going to un-break
the buildfarm.
