I was hoping it would help with the following gcc warning:
[35/657] Compiling C object src/shared/libsystemd-shared-248.a.p/bus-message-util.c.o
../src/shared/bus-message-util.c: In function ‘bus_message_read_dns_servers’:
../src/shared/bus-message-util.c:165:21: warning: ‘family’ may be used uninitialized in this function [-Wmaybe-uninitialized]
165 | r = in_addr_full_new(family, &a, port, 0, server_name, dns + n);

It actually doesn't, but the compiler has a point here: the code is specified
in sd_bus_error_map[], and it has no way of knowning that we want it to be a
positive value.
I think this should be an assert, because if this assumption fails, a
programming error has occured, something that'd want to catch.
