KVM: arm64: Remove is_protected_kvm_enabled() checks from hypercalls

Browse source

When pKVM is not enabled, the host shouldn't issue pKVM-specific
hypercalls and so there's no point checking for this in the pKVM
hypercall handlers.

Remove the redundant is_protected_kvm_enabled() checks from each
hypercall and instead rejig the hypercall table so that the
pKVM-specific hypercalls are unreachable when pKVM is not being used.
