Add an ftest that fills a small pool through the write-back cache and verifies the delayed ENOSPC is reported by fsync once per open handle, and is not reported to a newly opened handle. Document the asynchronous write-back error reporting in IO_PATHS_DESIGN.md and fix the alignment of the new assignment in dfuse_reply_entry(). Signed-off-by: Liang Zhen <zhen.liang@hpe.com>
