  KVM: SVM: Fix redundant updates of LBR MSR intercepts (2025-11-18 17:52:20 +0100)

----------------------------------------------------------------
Arm:

- Only adjust the ID registers when no irqchip has been created once
  per VM run, instead of doing it once per vcpu, as this otherwise
  triggers a pretty bad conbsistency check failure in the sysreg code.

- Make sure the per-vcpu Fine Grain Traps are computed before we load
  the system registers on the HW, as we otherwise start running without
  anything set until the first preemption of the vcpu.

x86:

- Fix selftests failure on AMD, checking for an optimization that was not
  happening anymore.
