[PATCH] nvdimm: Avoid wasting some memory.

sizeof(struct btt_sb) is 4096. When using devm_kzalloc(), there is a small memory overhead and, on most systems, this leads to 40 bytes of extra memory allocation. So 5036 bytes are expected to be allocated. The memory allocator works with fixed size hunks of memory. In this case, it will
