In LoongArch, get_numa_distances_cnt() was not in use, resulting in
a compiler warning.

Fix follow errors with clang-18 when W=1e:

arch/loongarch/kernel/acpi.c:259:28: error: unused function 'get_numa_distances_cnt' [-Werror,-Wunused-function]
  259 | static inline unsigned int get_numa_distances_cnt(struct acpi_table_slit *slit)
      |                            ^~~~~~~~~~~~~~~~~~~~~~
