cache: add pool deps for preload

Browse Source 
for_each_sub_lv() normally does not put  pool_lv into deps.

So for now go around it in 'lv_preload()' and add explicit
call with pool.

TODO: think about a better way, we want pool_lv deps only in certain
moments, so maybe for_each_sub_lv() needs new arg for this.
