t: Renamed LFS_T_CKDATA -> LFS_T_CK, implies LFS_T_CKMETA

Browse Source 
It really doesn't make sense to check data and not check metadata. We're
already traversing the metadata, so validating it adds very little
overhead, and how can we trust our data if we can't trust our metadata?

This renames LFS_T_CKDATA -> LFS_T_CK, which now also implies
LFS_T_CKMETA. This implication is done explicitly in lfsr_mtree_traverse
instead of doing anything fancy with flags.

Implying LFS_T_CKMETA also means one less configuration to support.
