Compared to the old code, this unblocks BLOCK_OP_TYPE_DATAPLANE, i.e.
you can now run a dataplane device on a BDS used as the mirror target.

This means that the target could require a different AioContext than the
source, which we can't support. So it seems unlikely to me that we can
lift this restriction.
