md: export helpers to stop sync_thread
Add new helpers:
void md_idle_sync_thread(struct mddev *mddev);
void md_frozen_sync_thread(struct mddev *mddev);
void md_unfrozen_sync_thread(struct mddev *mddev);
The helpers will be used in dm-raid in later patches to fix regressions
and prevent calling md_reap_sync_thread() directly.
