dhcp: minor cleanup of accept/decline functions in "nm-dhcp-client.c"

Browse Source 
- 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.
