md: raid10: wake up frozen array
When rescheduling a bio in raid10, we wake up the md thread, but if the array is frozen, this will have no effect. This causes the array to remain frozen for eternity. We add a wake_up to allow the array to de-freeze. This code is nearly identical to the raid1 code, which has this fix already.
