vmem->bitmap indexes the memory region of the virtio-mem backend at a
granularity of block_size. To calculate the index of target section offset,
the block_size should be divided instead of the bitmap_size.

When vIOMMU is enabled, the vq->used_phys is actually the IOVA not
GPA. So we need to translate it to GPA before the syncing otherwise we
may hit the following crash since IOVA could be out of the scope of
the GPA log size. This could be noted when using virtio-IOMMU with
vhost using 1G memory.
