[f2fs] Fix incorrect directory operations

In fs_test,
- For TestDirectoryReaddirRmAll of DirectoryTest,
    since results of readdir are not ordered by creation sequence in f2fs,
    check whether each readdir result is correct in an alternative way.

In f2fs,
- Use correct i_mode in GetProtocols.
- Check must_be_dir conditions in Rename and Unlink.
- Exclude ".." from results of Readdir.
- Set correct return value from Readdir.
- Add missing initialization for member variables of vnode.
- Check whether dir is unlinked before create or rename inside the dir.

Test: fx test directory-tests unlink-tests dot-dot-tests
