Subject: [PATCH v2 2/6] KVM: Documentation: Update the field name gfns and its
 description in kvm_mmu_page

Update the field 'gfns' in kvm_mmu_page to 'shadowed_translation' to be
consistent with the code. Also update the corresponding 'gfns' in the
comments. The more detailed description of 'shadowed_translation' is
already inlined in the data structure definition, so no need to duplicate
the text but simply just update the names.
