block: more check for replaced node
We use mirror+replace to fix quorum's broken child. bs/s->common.bs is quorum, and to_replace is the broken child. The new child is target_bs. Without this patch, the replace node can be any node, and it can be top BDS with BB, or another quorum's child. We just check if the broken child is part of the quorum BDS in this patch.
