fs: Fix link_path_walk to return -ENOENT on empty path
link_path_walk was returning 0 when passed with an empty path,
this lead calling code to assume that the struct nameidata nd
is valid and thus has a `last` field populated, which is not.
In the end causing a runtime crash.
This issue can easily be reproduced by running the command:
cat ""
