[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.
