Rename the memory block lookup helper to make the acquired reference explicit, add memory_block_put() to wrap put_device(), remove find_memory_block(), and use memory_block_get() as the single block-id based lookup interface. This makes it clearer to callers that a successful lookup holds a reference that must be dropped, reducing the chance of forgetting the matching put and leaking the memory block device reference.
