[PATCH 9/9] migration: Unexport migration_is_active()

[Avihai Horon]

After being removed from VFIO and dirty limit, migration_is_active() no
longer has any users outside the migration subsystem, and in fact, it's
only used in migration.c.

Unexport it and also relocate it so it can be made static.
