io_uring/zcrx: use dma_len for chunk size calculation
Buffers are now dma-mapped earlier and we can sg_dma_len(), otherwise,
since it's walking with for_each_sgtable_dma_sg(), it might wrongfully
reject some configurations. As a bonus, it'd now be able to use larger
chunks if dma addresses are coalesced e.g by iommu.
Fixes: 8c0cab0b7bf7 ("io_uring/zcrx: always dma map in advance")
