ksmbd: fix same UniqueId for dot and dotdot entries
[ Upstream commit 97550c7478a2da93e348d8c3075d92cddd473a78 ]
ksmbd sets the inode number to UniqueId. However, the same UniqueId for
dot and dotdot entry is set to the inode number of the parent inode.
This patch set them using the current inode and parent inode.
