PM: hibernate: Remove unused stub for saveable_highmem_page()

Browse Source 
When saveable_highmem_page() is unused, it prevents kernel builds
with clang, `make W=1` and CONFIG_WERROR=y:

kernel/power/snapshot.c:1369:21: error: unused function 'saveable_highmem_page' [-Werror,-Wunused-function]
 1369 | static inline void *saveable_highmem_page(struct zone *z, unsigned long p)
      |                     ^~~~~~~~~~~~~~~~~~~~~

Fix this by removing unused stub.

See also commit 6863f5643d ("kbuild: allow Clang to find unused static
inline functions for W=1 build").
