Fix geometry configured status check
Checking dma_domain->win_cnt is not sufficient to conclude that
geometry it set.
Either it should check dma_domain->geom_size also or it should
check dma_domain->win_arr as this is allocated when geometry is set.
We are using dma_domain->win_arr pointer check in this patch.
