Subject: [PATCH v4 1/2] KVM: VMX: rename 'kvm_area' to 'vmxon_region'

The name 'kvm_area' is misleading (as we have way too many areas which are
KVM related), what alloc_kvm_area()/free_kvm_area() functions really do is
allocate/free VMXON region for all CPUs. Rename accordingly.

No functional change intended.
