[BLKTAP]: Copy shared data before verification
As it is blktap verifies the metadata from the frontend in place.
This means we run the risk of the frontend changing the data after
we've verified it. This patch copies the data onto the stack before
verifying and using it to ensure we see a consistent snapshot.
