md: unlock mddev before reap sync_thread in action_store
Since the bug which commit 8b48ec23cc51a ("md: don't unregister sync_thread
with reconfig_mutex held") fixed is related with action_store path, other
callers which reap sync_thread didn't need to be changed.
Let's pull md_unregister_thread from md_reap_sync_thread, then fix previous
bug with belows.
1. unlock mddev before md_reap_sync_thread in action_store.
2. save reshape_position before unlock, then restore it to ensure position
not changed accidentally by others.
