Checking values in a function named check_keys() is unclean anyway. The original sin was commit 0545f6b887 "qapi: Better error messages for bad expressions", which checks the value of key 'name'. More sinning in commit 2cbf09925a "qapi: More rigorous checking for type safety bypass", commit c818408e44 "qapi: Implement boxed types for commands/events", and commit 967c885108 "qapi: add 'if' to top-level expressions". This commit does penance for the latter. The next commits will do penance for the others.
