From: Yu Kuai <redacted>

mddev_suspend() never stop sync_thread, hence it dones't make sense to
ignore suspended array in md_check_recovery(), which might cause
sync_thread can't be unregistered.

Before this patch, use stop_sync_thread() directly for syspended array
will hang because md_check_recovery() can't clear MD_RECOVERY_RUNING,
which is possible for dm-raid.
