[roll] Roll fuchsia [fxfs] Delay writeback_end for batches to do a single barrier.

Rather than doing a barrier between each batch or pushing a bunch of
background work to try to get some kind of parallelism, here we wait to
call writeback_end for all the batches by doing a single barrier at the
end for all of them.

Holding these writebacks open for longer shouldn't make a difference.
Getting a page in these ranges modified any time after the
writeback_begin will result in a single mark_dirty request, regardless
of if it is before or after the writeback_end.
