genlist : fix size hash issue when genlist layout sizing evaluated

Summary :
When genlist compressed, size width must updated after sizing eval,
but still hash is not changed after sizing eval, so wrong width are
applied.

so when sizing eval called, free all buckets to get updated width.

genlist: remove unnecessary data creation

Summary :
after using hash, sd is not needed on block_recalc
so it must be removed.

@fix
