[libvirt] [PATCH] rpc: Make the dispatch generator handle 'void name(void)' style procedures

Currently there are no such procedures in the protocol, but programming errors like a missing _args or _ret suffix on the structs in the .x files can create such a situation by accident. Making the generator aware of this avoids bogus errors from the generator such as: Use of uninitialized value in exists at ./rpc/gendispatch.pl line 967.
