Fix variable confusion in BufferSync().

As noted by Heikki Linnakangas, the previous coding confused the "flags"variable with the "mask" variable. The affect of this appears to be thatunlogged buffers would get written out at every checkpoint rather thanonly at shutdown time. Although that's arguably an acceptable failuremode, I'm back-patching this change, since it seems like a poor idea torely on this happening to work.
