[PATCH 2/2] arm64/kvm: Drop checking target CPU type on initializing module

[Gavin Shan]

The target CPU type is validated when KVM module is initialized.
However, we always have a valid target CPU type since commit
<bca556ac468a> ("arm64/kvm: Add generic v8 KVM target").

So it's unnecessary to validate the target CPU type at that time
and this just drops it.
