misc: mods: Fix segment_size overflow bug
...
The sg->length may happen to be a large size, and this
will overflow the local segment_size when accumulating
sg->length to it at line "segment_size += sg->length".
Since segment_size of MODS_DMABUF_GET_PHYSICAL_ADDRESS
structure is defined in u64 type, this patch fixes the
bug by changing the local varible to u64 as well.

drivers: mods: Assign dma_ops to the device
...
dummy_device created in mods test does not have dma_ops set to it.
So explicitly set the dma_ops of device to swiotlb_dma_ops.
