[Qemu-devel] [PATCH v4 21/22] libqtest: Drop now-unused qmp()

[Eric Blake <eblake@redhat.com>]

All callers have been converted to a form of qmp_cmd() or
qmp_args() that takes the command name with less boilerplate.
Therefore, we also know that all commands are using
interpolation, and can remove an assertion.

This also means that we have fixed the testsuite to comply with
-Wformat checking on the strings being interpolated for qmp()
(similar to what we previously did for strings used in hmp(), and
matching the checking present on qobject_from_jsonf()).
