libnm: assert that dbus_connection_allocate_data_slot() doesn't fail

Browse Source 
dbus_connection_allocate_data_slot() can only fail on ENOMEM, in which
case the immediately-following call to g_set_error() would also get
ENOMEM and abort. So just simplify and assert that the libdbus call
didn't fail.
