Subject: Avoid waiting for disk I/O completion

This improves performance quite a bit, and is not less safe.

* ext2fs/dir.c (diskfs_direnter_hard, diskfs_dirremove_hard,
diskfs_dirrewrite_hard): Pass diskfs_synchronous instead of 1 as wait
parameter to diskfs_file_update.
* ext2fs/truncate.c (diskfs_truncate): Likewise.
* libdiskfs/dir-init.c (diskfs_init_dir): Likewise.
* libdiskfs/dir-link.c (diskfs_S_dir_link): Likewise.
* libdiskfs/dir-rename.c (diskfs_S_dir_rename): Likewise.
* libdiskfs/dir-renamed.c (diskfs_rename_dir): Likewise.
* libdiskfs/file-set-trans.c (diskfs_S_file_set_translator): Likewise.
* libdiskfs/node-create.c (diskfs_create_node): Likewise.
* libdiskfs/node-drop.c (diskfs_drop_node): Likewise.
