Reverted LFS3_CKDATACKSUMREADS -> LFS3_CKDATACKSUMS

Browse Source 
LFS3_CKDATACKSUMREADS is just too much.

The downside is it may not be clear how LFS3_CKDATACKSUMREADS interacts
with the future planned LFS3_CKREADS (LFS3_CKREADS implies
LFS3_CKDATACKSUMS + LFS3_CKMETAREDUND), but on the flip side you may
actually be able to type LFS3_CKDATACKSUMS on the first try.
