Fix build error with !CONFIG_MIGRATION



migrate_huge_page_move_mapping() is declared as "extern int ..."
in include/linux/migrate.h for !CONFIG_MIGRATION,
which causes the build error like below:

  mm/mprotect.o: In function `migrate_huge_page_move_mapping':
  mprotect.c:(.text+0x0): multiple definition of `migrate_huge_page_move_mapping'
  mm/shmem.o:shmem.c:(.text+0x0): first defined here
  mm/rmap.o: In function `migrate_huge_page_move_mapping':
  rmap.c:(.text+0x0): multiple definition of `migrate_huge_page_move_mapping'
  mm/shmem.o:shmem.c:(.text+0x0): first defined here
