Re: [PATCH v2] drivers/base/memory: make memory block get/put explicit

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.
