KVM: arm64: selftests: Check ID regs are immutable after a failed run
Add a set_id_regs case covering ID register immutability when a vCPU's
first KVM_RUN fails after finalization but before
KVM_ARCH_FLAG_HAS_RAN_ONCE is set. The test provokes such a failure with
a PMUv3-enabled vCPU whose PMU is left uninitialized, then checks that
KVM_SET_ONE_REG on the feature and implementation ID registers, and
KVM_CREATE_DEVICE for a vGIC, are all rejected with -EBUSY.
