Subject: [PATCH 04/10] kvm: always update the MPX model specific register

O-Subject: [RHEL-7.2 qemu-kvm PATCH 3/8] kvm: always update the MPX model specific register
Bugzilla: 1233350

From: Paolo Bonzini <pbonzini@redhat.com>

The original patch from Liu Jinsong restricted them to reset or full
state updates, but that's unnecessary (and wrong) since the BNDCFGS
MSR has no side effects.
