zhenwei pi 72775cad7f virtio-blk: fix implicit overflow on virtio_max_dma_size 
[ Upstream commit fafb51a67f ]

The following codes have an implicit conversion from size_t to u32:
(u32)max_size = (size_t)virtio_max_dma_size(vdev);

This may lead overflow, Ex (size_t)4G -> (u32)0. Once
virtio_max_dma_size() has a larger size than U32_MAX, use U32_MAX
instead.
