mm/sparse: fix "unused function 'pgdat_to_phys'" warning

W=1 build with clangs complains:

mm/sparse.c:347:27: warning: unused function 'pgdat_to_phys' [-Wunused-function]
static inline phys_addr_t pgdat_to_phys(struct pglist_data *pgdat)
                             ^
1 warning generated.

pgdat_to_phys() is only used by functions defined when
CONFIG_MEMORY_HOTREMOVE=y.

Move pgdat_to_phys() under #ifdef CONFIG_MEMORY_HOTREMOVE
to make clang happy.
