It can't. This patch just prevents md.c from going crazy as a
consequence of a bug elsewhere in the backend that causes higher
levels of the backend to request a garbage block number.
The patch doesn't fix the underlying problem (ie, whatever higher-level
bug might cause this); it just limits the extent of the bad
consequences...
