KVM: remove redundant declarations

Changing s390 code in kvm_arch_vcpu_load/put come across this header
declarations. They are complete duplicates, not even useful forward
declarations as nothing using it is in between (maybe it was that in
the past).

This patch removes the two dispensable lines.
