qmp_query_cpu_definitions() passes @errp to get_max_cpu_model(), then
frees any error it gets back. This effectively ignores errors.
Dereferencing @errp is wrong; see the big comment in error.h. Passing
@errp is also wrong, because it works only as long as @errp is neither
@error_fatal nor @error_abort. Introduced in commit 38cba1f4d8
"s390x: return unavailable features via query-cpu-definitions".
No caller actually passes such @errp values.
Fix anyway: simply pass NULL to get_max_cpu_model().
