Subject: [PATCH] KVM: nVMX: fix lifetime issues for vmcs02

commit 4fa7734c62cdd8c07edd54fa5a5e91482273071a upstream.

free_nested needs the loaded_vmcs to be valid if it is a vmcs02, in
order to detach it from the shadow vmcs.  However, this is not
available anymore after commit 26a865f4aa8e (KVM: VMX: fix use after
free of vmx->loaded_vmcs, 2014-01-03).

Revert that patch, and fix its problem by forcing a vmcs01 as the
active VMCS before freeing all the nested VMX state.
