xfs: ensure sync write errors are returned
xfs_file_aio_write() only returns the error from synchronous flushing of the data and inode if error == 0. At the point where error is being checked, it is guaranteed to be > 0. Therefore any errors returned by the data or fsync flush will never be returned. Fix the checks so we overwrite the current error once and only if an error really occurred.
