rust: dma: rename dma_handle to dma_address

The `dma_handle` naming is inherited from the C API, but what this
really describes is the device DMA address; everything named
`dma_handle` is actually a `dma_addr_t`.

This naming introduces some confusion on the Rust API side, as handles
are supposed to be opaque tokens, yet we were doing address computation
on values returned by `dma_handle`.

Rename `dma_handle` to `dma_address` while nova-core is still its only
user.
