Yuezhang Mo 2ff61106d6 exfat: support handle zero-size directory
[ Upstream commit dab48b8f2fe7264d51ec9eed0adea0fe3c78830a ]

After repairing a corrupted file system with exfatprogs' fsck.exfat,
zero-size directories may result. It is also possible to create
zero-size directories in other exFAT implementation, such as Paragon
ufsd dirver.

As described in the specification, the lower directory size limits
is 0 bytes.

Without this commit, sub-directories and files cannot be created
under a zero-size directory, and it cannot be removed.
