lvresize: improve usepolices

Browse Source 
lvresize --usepolicy requires resized LVs to be active.
(So it's not only required for shared VG).

The test for active pool needs to use lv_info to query 'layer'
otherwise the pool is considered inactive if it was not activated
explicitely - thun 'implicit' activation with VDO or ThinLV was
not managed by --usepolicy option.
