KVM: TDX: restore host xsave state when exit from the guest TD
On exiting from the guest TD, xsave state is clobbered; restore it.
Do not use kvm_load_host_xsave_state(), as it relies on vcpu->arch
to find out whether other KVM_RUN code has loaded guest state into
XCR0/PKRU/XSS or not. In the case of TDX, the exit values are known
independent of the guest CR0 and CR4, and in fact the latter are not
available.
