Christoph Hellwig e163cbde98 xfs: avoid a few disk cache flushes 
There is no need for a pre-flush when doing writing the second part of a
split log buffer, and if we are using an external log there is no need
to do a full cache flush of the log device at all given that all writes
to it use the FUA flag.
