selftests: kvm: fix state save/load on processors without XSAVE

[ Upstream commit 54577e5018a8c0cb79c9a0fa118a55c68715d398 ]

state_test and smm_test are failing on older processors that do not
have xcr0.  This is because on those processor KVM does provide
support for KVM_GET/SET_XSAVE (to avoid having to rely on the older
KVM_GET/SET_FPU) but not for KVM_GET/SET_XCRS.
