sd: omit zero-initialization for csd[4] and cid[4]

After a review of the usage of csd[4] and cid[4], it has been determined that zero-initialization can be omitted. It can be expected from successful operations that data will be appropriately written back from the underlying layer. Signed-off-by: Pisit Sawangvonganan <[email protected]>
