dm cache metadata: use dm-space-map-metadata.h defined size limits
Commit 7d48935e cleaned up the persistent-data's space-map-metadata
limits by elevating them to dm-space-map-metadata.h. Update
dm-cache-metadata to use these same limits.
The calculation for DM_CACHE_METADATA_MAX_SECTORS didn't account for the
sizeof the disk_bitmap_header. So the supported maximum metadata size
is a bit smaller (reduced from 33423360 to 33292800 sectors).
