KVM: arm64: Handle trapping of FEAT_LS64* instructions

We generally don't expect FEAT_LS64* instructions to trap, unless
they are trapped by a guest hypervisor.

Otherwise, this is just the guest playing tricks on us by using
an instruction that isn't advertised, which we handle with a well
deserved UNDEF.
