KVM: SVM: Update svm->ldr_reg cache even if LDR is "bad"
Update SVM's cache of the LDR even if the new value is "bad". Leaving
stale information in the cache can result in KVM missing updates and/or
invalidating the wrong entry, e.g. if avic_invalidate_logical_id_entry()
is triggered after a different vCPU has "claimed" the old LDR.
