Commit b7724fdf85
appears to have caused a regression, where `ip4`, `gw4`, `ip6`, `gw6`
were converted to `ipv4.address`, `ipv4.gateway` etc.
This causes bootproto (or `ipv4.method`) to remain `dhcp`, as noted in https://github.com/ansible/ansible/issues/36615
This commit only reverts the key-value pairs to the original names,
which is in line with both expectation (manual ip addr == no dhcp) and
the language used in the playbook, which is, for example, "ip4" not
"ipv4.address"
