KVM: x86: Update trace function for nested VM entry to support VMX

Browse source

Update trace function for nested VM entry to support VMX. Existing trace
function only supports nested VMX and the information printed out is AMD
specific.

So, rename trace_kvm_nested_vmrun() to trace_kvm_nested_vmenter(), since
'vmenter' is generic. Add a new field 'isa' to recognize Intel and AMD;
Update the output to print out VMX/SVM related naming respectively, eg.,
vmcb vs. vmcs; npt vs. ept.

Opportunistically update the call site of trace_kvm_nested_vmenter() to
make one line per parameter.
