[PATCH] md: make sure resync gets started when array starts. We weren't actually waking up the md thread after setting MD_RECOVERY_NEEDED when assembling an array, so it is possible to lose a race and not actually start resync. So add a call to md_wakeup_thread, and while we are at it, remove all the "if (mddev->thread)" guards as md_wake_thread does its own checking.
