Subject: [PATCH] KVM: SVM: Fix reserved fields of struct sev_es_save_area

Reserved fields of struct sev_es_save_area are named by their order of
appearance, but right now they jump from reserved_5 to reserved_7. Rename
them with the correct order.

Fixes: 6d3b3d34e39eb ("KVM: SVM: Update the SEV-ES save area mapping")
