[libnftables PATCH] nat: xml: fix wrong node name in snprintf

[Arturo Borrero Gonzalez <arturo.borrero.glez@gmail.com>]

This patch renames all <nat_type> nodes to <type> in nat expr.
A bug is fixed, since the default option in snprintf was already
<type>.

This follows the pattern of avoid prefixing XML nodes.

Note that this is mostly reverting what was done at:
31e34c3 (nat: xml: rename node type to nat_type).
