O-Subject: [RHEL7.9 qemu-kvm-rhev PATCH 6/6] target/i386: enable monitor and ucode revision with -cpu max
Bugzilla: 1791653

These two features were incorrectly tied to host_cpuid_required rather than
cpu->max_features. As a result, -cpu max was not enabling either MONITOR
features or ucode revision.
