mnt: Remove dead code which might prevent from building

Browse Source 
Clang, in particular, is not happy about dead code:

fs/namespace.c:135:37: error: unused function 'node_to_mnt_ns' [-Werror,-Wunused-function]
  135 | static inline struct mnt_namespace *node_to_mnt_ns(const struct rb_node *node)
      |                                     ^~~~~~~~~~~~~~
1 error generated.

Remove a leftover from the previous cleanup.
