[Qemu-devel] [PULL 02/25] libqtest: Clean up how we read device_del messages

[Markus Armbruster]

qtest_qmp_device_del() still uses the qmp("") hack to receive a
message, even though we have qmp_receive() since commit 66e0c7b187e.
Put it to use.

Bonus: gets rid of empty format strings.  A step towards compile-time
format string checking without triggering -Wformat-zero-length.
