Subject: [PATCH 13/16] target/i386: adjust for missing VMX features

O-Subject: [RHEL8.2/rhel qemu-kvm PATCH 13/15] target/i386: adjust for missing VMX features
Bugzilla: 1689270

vmx-exit-load-perf-global-ctrl and vmx-entry-load-perf-global-ctrl
have only been added to kernel 5.4, so disable them in RHEL until
we add them to the kernel.  At that point, they could be added back
to a new machine type.
