KVM: nSVM: Mark all of vmcb02 dirty when restoring nested state
When restoring a vCPU in guest mode, any state restored before
KVM_SET_NESTED_STATE (e.g. KVM_SET_SREGS) will mark the corresponding
dirty bits in vmcb01, as it is the active VMCB before switching to
vmcb02 in svm_set_nested_state().
Hence, mark all fields in vmcb02 dirty in svm_set_nested_state() to
capture any previously restored fields.
Fixes: cc440cdad5b7 ("KVM: nSVM: implement KVM_GET_NESTED_STATE and KVM_SET_NESTED_STATE")
