KVM: nVMX: reorganize initial steps of vmx_set_nested_state
Commit 332d079735f5 ("KVM: nVMX: KVM_SET_NESTED_STATE - Tear down old EVMCS state before setting new state", 2019-05-02) broke evmcs_test because the eVMCS setup must be performed even if there is no VMXON region defined, as long as the eVMCS bit is set in the assist page. While the simplest possible fix would be to add a check on kvm_state->flags & KVM_STATE_NESTED_EVMCS in the initial "if" that covers kvm_state->hdr.vmx.vmxon_pa == -1ull, that is quite ugly. Instead, this patch moves checks earlier in the function and conditionalizes them on kvm_state->hdr.vmx.vmxon_pa, so that vmx_set_nested_state always goes through vmx_leave_nested and nested_enable_evmcs.
