Renamed scmp -> cmp

- enum lfs3_scmp -> enum lfs3_cmp
- cmp -> cmp

lfs3_scmp_t is still used as the type, as the s prefix indicates the
type is signed, usually for muxing with error codes.

I think that led to the enum also being named lfs3_scmp, but that's not
quite right.

But none of this really matters because enums are so useless and broken
in C.
