Is it really necessary? Does it matter whether it must be ACTIVE/POSTCOPY_ACTIVE/DEVICE? I guess no. The external user is trying to detect whether migration is running or not, as simple as that. To make the migration_is*() APIs even shorter, let's use migration_is_running() for outside worlds. Internally there're actually three places that literally needs migration_is_active() rather than running(). Keep that an internal helper. After this patch, we finally only export one helper that allows external world to try detect migration status, which is migration_is_running().
