Mark Johnston 369706a6f8 buf: Fix the dirtybufthresh check
dirtybufthresh is a watermark, slightly below the high watermark for
dirty buffers.  When a delayed write is issued, the dirtying thread will
start flushing buffers if the dirtybufthresh watermark is reached.  This
helps ensure that the high watermark is not reached, otherwise
performance will degrade as clustering and other optimizations are
disabled (see buf_dirty_count_severe()).

When the buffer cache was partitioned into "domains", the dirtybufthresh
threshold checks were not updated.  Fix this.
