Mike Snitzer 687cf4412a dm cache metadata: verify cache has blocks in blocks_are_clean_separate_dirty()
Otherwise dm_bitset_cursor_begin() return -ENODATA.  Other calls to
dm_bitset_cursor_begin() have similar negative checks.

Fixes inability to create a cache in passthrough mode (even though doing
so makes no sense).
