A few functions defined but not used. This, in particular,
prevents kernel builds with clang, `make W=1` and CONFIG_WERROR=y:
lib/maple_tree.c:351:21: error: unused function 'mte_set_full' [-Werror,-Wunused-function]
351 | static inline void *mte_set_full(const struct maple_enode *node)
| ^~~~~~~~~~~~
lib/maple_tree.c:356:21: error: unused function 'mte_clear_full' [-Werror,-Wunused-function]
356 | static inline void *mte_clear_full(const struct maple_enode *node)
| ^~~~~~~~~~~~~~
lib/maple_tree.c:361:20: error: unused function 'mte_has_null' [-Werror,-Wunused-function]
361 | static inline bool mte_has_null(const struct maple_enode *node)
| ^~~~~~~~~~~~
Fix this by dropping unused functions.
See also commit 6863f5643dd7 ("kbuild: allow Clang to find unused static
inline functions for W=1 build").
Fixes: 6e7ba8b5e238 ("maple_tree: mte_set_full() and mte_clear_full() clang-analyzer clean up")
Fixes: 54a611b60590 ("Maple Tree: add new data structure")
