device: improve "nm-device-logging.h" to support a self pointer of NMDevice type

"nm-device-logging.h" defines logging macros for a NMDevice instance.
It also expects a "self" variable in the call environment, and that
variable had to be in the type of NMDevice or the NMDevice subclass.

Extend the macro foo, so that @self can be either a NMDevice* pointer
or a NMDevice$SUBTYPE.

Of course, that would have always been possible, if we would simply cast
to "(NMDevice *)" where we need it. The trick is that the macro only
works if @self is one of the two expected types, and not some arbitrary
unrelated type.
