expr: basic support for printing nft_data_reg in XML format

nft_data_reg now is printed in XML according to what it contains

<data> nodes have been also renamed.

Arturo Borrero Gonzalez says:

====================
cmp is using <cmpdata> <cmpdata> has <data_reg></data_reg> which
can also be redundant.

But all around the XML printing (including sets, an incoming patch)
i've been nesting the data_reg into another XML node, so you could
easily see (also the XML parser) the difference between (for example.
in set) nft_set_elem->key and nft_set_elem->data.

As I needed to nest in nft_set_elem I decided to follow a constant
line and do nest all data_reg.
