These functions provide an easy API for checking all metadata/data
checksums in the filesystem:
// Check the filesystem for metadata errors
int lfsr_fs_ckmeta(lfs_t *lfs);
// Check the filesystem for metadata + data errors
int lfsr_fs_ckdata(lfs_t *lfs);
These are more-or-less the same as calling lfsr_fs_gc with
LFS_GC_CKMETA/CKDATA, but don't involve the gc/traversal-invalidation
machinery, and may be a bit easier for users to pick up.

Unfortunately, for simple wrappers, we're again hit with a somewhat
surprising code cost:
code stack
before: 36288 2680
after: 36472 (+0.5%) 2680 (+0.0%)
But I think we can again blame the high overhead of LFS_TRAVERSAL/
lfsr_mtree_gc. We should look into reducing/deduplicating this logic...
