Jeff Cody 5a6684d2b9 block: add helper function to determine if a BDS is in a chain 
This is a small helper function, to determine if 'base' is in the
chain of BlockDriverState 'top'.  It returns true if it is in the chain,
and false otherwise.

If either argument is NULL, it will also return false.
