cache: fix lvdisplay --maps
'lvdisplay -m' tried to go through NULL policy settings,
when such policy was not defined for CachedLV.
Patch is fixing display of cache-pool without defined settings,
as this is now a valid pool and we mostly want users to define
these settings when actually really caching a LV.
