hv: nested: remove vcpu->arch.nested.current_vmcs12_ptr

Browse Source 
This variable represents the L1 GPA of the current VMCS12.  But it's
no longer needed in the multiple active VMCS12 case, which uses the
following variables for this purpose.

- nested->current_vvmcs refers to the vvmcs[] entry which contains the
  cached current VMCS12, its associated VMCS02, and other context info.

- nested->current_vvmcs->vmcs12_gpa refers to the L1 GPA of this
  current VMCS12.
