dhcp: minor cleanup of accept/decline functions in "nm-dhcp-client.c"
- assign the result of NM_DHCP_CLIENT_GET_CLASS() to a local variable. It feels nicer to only call the macro once. Of course, the macro expands to plain pointer dereferences, so there is little difference in terms of executed code. - handle the default case with no virtual function first.
