Subject: [PATCH 5/9] mm: Mark functions as static in migrate.c

Mark functions as static in migrate.c because they are not used outside
this file.

This eliminates the following warnings in mm/migrate.c:
mm/migrate.c:1595:6: warning: no previous prototype for ‘numamigrate_update_ratelimit’ [-Wmissing-prototypes]
mm/migrate.c:1619:5: warning: no previous prototype for ‘numamigrate_isolate_page’ [-Wmissing-prototypes]
