md: md_stop_writes requires mddev_lock.
As md_stop_writes manipulates the sync_thread and calls md_update_sb,
it need to be called with mddev_lock held.
In all internal cases it is, but the symbol is exported for dm-raid to
call and in that case the lock won't be help.
Do make an exported version which takes the lock, and an internal
version which does not.
