Rename {vmx,nested_vmx}_vcpu_setup to {vmx,nested_vmx}_vmcs_setup,
to match what they really do.

No functional change.

May be we should rename vmx_vcpu_reset() to vmx_vmcs_reset()  as well  ?

Not really. vmx_vcpu_reset() not only resets vmcs but also the emulated 
field of vmx vcpu.

It would be a better organization of the code if the resetting of the 
VMCS fields were placed in a separate function.
