pgsql: Remove redundant fetch of the recent flush pointer in WalSndWait

Remove redundant fetch of the recent flush pointer in WalSndWaitForWal.

In WalSndWaitForWal(), we fetch a recent flush pointer both outside the
loop and inside the loop. But we start using RecentFlushPtr only after we
fetch it inside the loop. So we can remove one outside the loop.
