Commit Message

Markus Armbruster July 30, 2018, 8:33 a.m. UTC 
Leaving interpolation into JSON to qmp() is more robust than building
QMP input manually, as explained in the recent commit "tests: Clean up
string interpolation into QMP input (simple cases)".

migrate_recover() builds QMP input manually because wait_command()
can't interpolate.  Well, it can since the previous commit.  Simplify
accordingly.

Bonus: gets rid of a non-literal format string.  A step towards
compile-time format string checking without triggering
-Wformat-nonliteral.
